More Math and Fun!

Updated on June 17, 2018

If you want to torture yourself more, let's get over with!

If you followed me from the other tutorials, then you are ready to learn more in on our own way. Wish Math teachers were more open to real life examples and add some humour to it.

But how can we change the system when, this system wants to change your life, and at times make it miserable. Like before also, hubs are limited and we go to the point without beating the bushes.


Venetian merchants needed a way to calculate left overs or over productivity. If they had caught fish for a day and knew that probably more than half would return a profit, then they needed a way to calculate that amount, because or the leftover would be thrown out or they could buy salt in order to preserve it for other occasions.

Now the easy part of a half is that is the total divided by two, but what about a third or a fourth or one hundredth as in 1 cent from a hundred ?

The invention of the % sign

In the XV century Monks and merchants from Italy ( remember the merchant of Venice?) introduced the word 'PER CENTO', that even today is used as 'per cent'. Abbreviations made it look like this P/C now when you start writing faster eventually you will evolve a language or a sign, right? Just see how your signature settle into what it is now. P/C path the way for % by the XVIII century, Period. So the usage of the sign, was to divide the number to the left for one hundredth.


80% means 80/100 do you follow me?

Now we cannot use it for math just like, let's say 80% of 28 won't work using it like


We have to convert 80% into its decimal equivalent which is .80

Rule to remember " take the percent sign off and add the dot two digits to the left

80%>>>>>>>>>>>>>>> 0.80

What you did was divide 80 by 100, which resulted in 80/100= 0.80

Now we are ready to use it in math:

0.80(28)= 22.4


If you are catching up with me you might already have figured out how to convert from decimal to percent

0.5 is easy, you move the period sign or dot two digits to the right which will make it:

0.5>>>>>> 50

and of course you add the % sign to that metamorphosis: 50%

example: write 8 as percent.,

8>>>> 8--.>>>>> you have to fill the gaps to the right with zeroes>>>> 800

the answer will be then 800%

Listen, guys! practice is the key...told you, this thing was like learning a new language!


Focus on the definition: "a part of an entire object" so these monks and merchants came out the silly representation for fractions"/" there was no typewriters, not windows seven, only a sheet and perhaps a quill....who knows, forget about light at nights.

Thomas Alva Edison invented the light bulb in 1878. And poor Thomas was kicked out of school in first grade for being stupid. Mom had to home school the boy...who eventually made his first dollars printing his own newspaper on a wagon, at 12 yrs of age...See? Would you give up on math, only because these teachers want you to suffer like they did?

SO 1/2 is one half

3/4 is 3 parts of the total that are four parts, and so on.

Now as we said in proportions, two ratios are equal if they comply with the statement. a/b=c/d

That's why fractions make 1/2=2/4 or


I just multiplied 3 times 5 and; 8 times 5 too ( if you need a break go ahead pal!)

If we have a pizza pie and it is sliced in 8 pieces...and I eat only can you say it in fractions?

I eat 1/8 of the whole pizza. Period! (don't break your head, almost done my friend)

Math and Mith
Math and Mith


A ratio shows the relative sizes of two or more values. A quick example, for every boy being born in some 'country', there will be 2 girls being born, the ratio will be like this


Why we talk about ratios if they make no sense at all? Ratios are needed for proportions that compare two ratios with their own rules, that probably you hated it anyway, huh?


We see a boy and three girls.....

The ratio of the picture will be



Is what teachers came out with..."Is the statement...Gees!.. that makes two ratios equal". Simple!

a:b=c:d or

better said


Important rule to use: always..always! you follow me?

In order to make the statement a veracity or true statement;

bxc=axd.... ((use mnemonics, what the heck! baccardi=andy, sorry teachers!))

examples :

3/4 = x/12

what is the value of 'x'?

use your bacardi=Andy b.c=a.d

make sure to keep the sequence of the original lay out: a/b=c/d

so if we are smart already..

3x12=4(X) (Mister bouncer is coming)


( mister bouncer will make number 4 be crushed by 36 for trying to scape from x)






Before time Romans and Etruscans wanted to rule our lives even with numbers like X, V, D, L and that really suck!

To make it easier lets call this "place value" thing a game of taking a small dark ball and play around moving it left or right of these players or numbers.

17.591 is our example

Everything to the left is a number.

For instance 7 represents the player number 7, Now player number 1 to his LEFT is 10 times bigger ...

to the right, of course are the lower players.

Player 5 is what we recognize better as 0.5 which means was degraded from the fraction 5/10=0.5

Player 9 is one hundredth smaller in speed and quick is recognized by itself as the famous 0.09 or in fractional designation 9/100. That's a tiny little thing, maybe an amoeba Basketball player.LOL!

Well guys, don't break your head more! this is it for now....just pass this hub on...Mister Bouncer and I need to have fun too. Rock on, baby!! Who put a piece of chewed bubble gum and a tack on my seat???


1/2 = 0.5 = 50/100

3/4=0.75 = 30/40




3(5)/4(5) + 2(4)/5(4)

15/20+ 8/20=

23/20.... which can be reduced to a number with decimals 23/20= 1.15 which can be represented as 1 15/100


Both fractions were multiplied by 1, which didn't alter the final solution, but this time we made sure we multiplied by 5/5, and 4/4

3/4(5/5)+ 2/5(4/4)......THIS was done in order to have a common divisor which was 20

    well, according to our calculations we can arrange the final reduction to 1 15/100 or 1.15. Thanks for the comment and glad you caught with that one.

    I don't know much about math.. but I believe you forgot to fix (reduce?) the final fraction.. 23/20=

    hello JT,

    You have a point then! Who wouldn't like to learn Calculus and save money on their student loan? Will work on that hub shortly my friend, but we need to make it look easier than our Analythical books. Thanks my friend!

    Hi Lord,

    Calculus will help them figure out how to buy al those gifts they would like to have on thier few dollars;-)


  • Lord De Cross profile image

    Joseph De Cross 6 years ago from New York

    Good tip JT,

    The thing is..or I think people nowadays is busier about the holiday spirit than Calculus, but I understand your suggestion. We will work on a hub on this subject. Thanks for stopping by.

    There you go again making Math easy for the masses again. NOw if you can just do that Calculus hub the masses so desperately need. ;-)

    Hi Cristina! LOL!

    Thought you left amiga. Salamat for your insightful comments, you are actually a Teacher, so your opinions get double vote up..right? Thanks!

    Oh, you're right...the system stinks!!

    But I will pass the word if I know of anyone...
