What is 30.5 percent of 122?

Answer 1

The first thing to note is that percent means that number over 100. Thus, 30.5% can be rewritten as 30.5/100. The next thing to note is that "of" in mathematics means "multiplied by." For example 4 groups of 10 means 4x10. Thus the question can be written as 30.5/100 x 122. Calculating this gives us 37.21, so 30.5% of 122 is 37.21
