Answer 1

247.6

Explanation:

You can find the percent of any number using proportions. A proportion is an equation between two equal ratios. Write two ratios where one relates the percents and the the numbers that correspond to those percents.

Here it would be:

300/ 100 = 742.8/ x

Solve by cross multiplying.

300x = 74280

Divide by 300.

x = 247.6
