Express 0.5 as a percent

The mathematical process in converting a decimal to a percent is as follows:

Convert 0.5 to a percent:

"Percent" means "per 100" or "over 100". So, to convert 0.5 to percent we rewrite 0.5 in terms of "per 100" or over 100.

Multiply 0.5 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

0.5 × 1 × 100/100 = 50/100

50/100 is 50 over 100 and means 50 per 100.

50 "per 100" means 50 "percent" or 50%.

Therefore, we have shown that

0.5 = 50%
