"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.

\[ \frac{0.5}{1} \times \frac{100}{100} = \frac{50}{100} \]50/100 is 50 over 100 and means 50 per 100.

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