How do you convert between fractions, decimals and percentages?
For example, 7/10 is the same as 0.7 and 70%. Percentages are actually all fractions out of 100. 70% is 70/100, 50% is 50/100, etc. When these are written as fractions they should be simplified so the denominator is as small as possible, which turns 50% into 1/2 because 50 and 100 can both be divided by 50 here. The decimal point is same as the percentage divided by 100, so the numbers themselves will be the same: 62% = 0.62
