What we did in class today is learn how to change from fraction to decimal to percent but you can do it any which way.
The first thing we did was change a fraction into a decimal.
To do that, we just have to divide the numerator with the denominator.
The second thing we did is change the decimal to a percent.
To do that, we have to multiply the decimal by 100 because percent is out of 100.
That is the way you can do it but don't have to do it that way because there are other ways you can do it too.
You can change from decimal to fraction to percent and percent to fraction to decimal
Decimal to fraction to percent
Decimal to fraction. First, whatever number that is after the decimal is 1 in the denominator. Second, you count how many numbers are before the decimal. If the number is 2, then there will be 2 zeros and you put the zeros before the 1 in the denominator.
Fraction to percent is you just have to make the denominator 100 and what you do to the denominator you do to the numerator.
Percent to fraction to decimal
Percent to fraction is if the number is not a decimal. First, you just have to take the percent number and put it as the numerator and make the denominator 100.
But if the percent is a decimal, you just count how many numbers are there before the decimal, you add a 0 at the bottom as a denominator to how many there are. Whatever the number is after the decimal, you put a 1. Then you put the percent number the numerator and make the denominator the number that you made by how many numbers before the decmial plus the 1 that is after the decimal.
Fraction to decimal. It already says it at the top.
