Remember that 23% means ^{23}/_{100}. Thus 23% is the same as 0.23.
To convert a fraction to a percent, first divide the numerator by the denominator.Â Then multiply the decimal by 100.Â
e.g. the fraction ^{4}/_{5} = 0.8
0.8 x 100 = 80
Therefore, the fraction ^{4}/_{5} is equivalent to 80%
Example 1
Write ^{2}/_{25} as a percent
Solution
^{2}/_{25} = 2 Ã· 25 = 0.08
= 0.08 x 100 = 8
Therefore, the fraction ^{2}/_{25} is equivalent to 8%
Example 2
Write ^{7}/_{4} as a percent
Solution
^{7}/_{4} = 7 Ã· 4 = 1.75
1.75 x 100 = 175
Therefore, the fraction ^{7}/_{4} is equivalent to 175%
