Converting Between Fractions, Decimals, and Percentages

Alright, so we've mastered fractions, decimals, and percentages, so let's quickly learn how to convert between them. This is important if you want to do calculations where you apply some percentage to a value, or a million other every day scenarios. Don't worry, it's easy!

amazing ur explanation is more better than my teacher bruhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

[@supercoolninja]

35 % in fraction = 7/20 because 35 / 5 = 7 and 100 / 5 = 20.
0.64 in fraction = 16/25 because 64/4 = 16 and 100/4 = 25.
82% in decimal = 0.82 we just need to place the , 2 step in left side.
4/5 in decimal = 0.8 we just need to find how to set the denominator to 10 by multiplying the numerator and denominator with the same number and then move the , one step in left.
14/50 in percentage = 28% you first need to have it in the decimal value so 14 / 50 is 0.28 then you need to multiply this number per 100.
0.19 in percentage = 19% you just need to multiply this number per 100 because you already have the decimal value.

[@kazziodex9561]

Elaborate sir. 35% can also be 35/100. How did you figure out that you needed to divide 35 with 5 ?

[@supercoolninja]

@@kazziodex9561
To simplify a fraction, you need to divide both the numerator (the top number) and the denominator (the bottom number) by their greatest common divisor (GCD).
The GCD is the largest number that divides both the numerator and the denominator without leaving a remainder. Here's a step-by-step guide on how to do this:
For example, if you have the fraction 35/100 ​, 35 is the numerator and 100 is the denominator.
List the factors of both the numerator and the denominator :
Factors of 35: 1, 5, 7, 35
Factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100
The common factors are: 1, 5
The greatest common factor is 5.
Divide both 35 and 100 by 5.
So, 35/100​ simplifies to 7/20​.
If the numerator is a prime number and it doesn't divide the denominator, the fraction is already in its simplest form.
so you know that you cannot do more simple than that because 7 is a prime number, so that's how you manage to get the same number to divide with.
I hope that's clear, do not hesitate if you have more question. i'm also learning maths.😃

I feel 0.64 should have just been 64/100, I know you simplified but I thought we were going over the basics, didn't realize you simplified by diving by 4 took me a minute to figure that out or should have stated to simply as well. I got everything right except the first 2 because I didn't simplify.

[@ProfessorDaveExplains]

You always have to simplify.

[@astroyeaster9464]

Trick I found because I was confused, you can divide 0.64 and 100 with the 4 to simplify it. Worked with 35% too, divide 35 and 100 with 5 and then you get the simplified equation.

I don’t know why, but on the test questions, converting to decimals and percentages was easy. But no matter what I did I couldn’t solve the conversion to fractions. I’m probably missing a step or something

[@prachethakikkeri1384]

Me too

[@scratchingcatclaw]

I think I figured it out. I hope this helps.
35% = 7/20 is just 35÷5/100÷5, because if you multiply 7 and 20 by 5 then they become 35 and 100.
0.64 = 16/25 because 64÷4/100÷4 are 16 and 25. Same thing as above.
This means that if you answered 35/100 and 64/100 (like me) then you're technically correct, it's just that your answer is rounded up to 100.
