Need to work out fraction as a %
if 112 children walk to school and there are 280 children in the school what % of them walked?

Hey there, just divide 112 by 280 and multiply by 100, 112/280=0.4, and 0.4*100=40%. Therefore, 112/280 as a percent is 40%

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
