The symbol used to show percent is “%” so 17 percent would be 17%. The “17” is the “part” and the “%” is the whole which means that 17% can also be shown as 17/100.
Converting Fractions to Percentages:
To convert a fraction to a percentage you need to divide the numerator of the fraction by the denominator.
For example, let’s look at the fraction 5/8. The number “5” is the numerator and the number “8” is the denominator so we need to divide 5 by 8 or 5 ÷ 8 = 0.625. The 0.625 can then be rounded up. To do this you look at the last number on the right. In this case we have a “5”. When a number is 5 to 9, the number immediately before it gets rounded up. This would make the “2” become a “3”. If the last number to the right is a 0 to 4, we round the number immediately to the left down such as if the number were 0.821 it would become simply 0.082. In our case, 0.625 can be rounded up to read 0.63.
Now we must convert 0.63 (or .63 as we can take away the “0”) to a percentage. To do this we must move the decimal point two spaces to the right of its current position. This means .63 becomes 63. The decimal point is then converted back into the percentage symbol “%” so we have 63%. This shows us that 5/8 is the same as 63%.
