you turn the decimal into a fraction then you turn the fraction into a whole number and add a percent sign
You take however many times the denominator goes into the numerator as a whole number. For example, 6/2 would be 3. Then take the remaining fraction and turn it into a decimal. For example, 7/2 would be 3 and 1/2 left over or 3.5. Just take the whole number and turn the fraction left over into a decimal add-on
If you know how to turn a mixed number into a fraction and a fraction into a decimal do that then make it negative.
divide the top number of the fraction by the bottom number to get your decimal. To turn that into a fraction, multiply by 100 and then add your % sign. e.g. 2/4---> 2 divided by 4 = 0.5 0.5 x 100= 50%
Ah, what a happy little question we have here. If we look closely, we can see that 0.4545454545 is a repeating decimal. To turn it into a fraction, we can call it x and subtract it from 100x to get a whole number. This gives us the fraction 5/11, a beautiful and harmonious representation of our repeating decimal.
