Question

At birth a newborns head is about 25% of its total length. Gavin was 18 inches. How many inches was his head

Answer 1

Ava, to find percent, you turn the percent into a decimal by moving the decimal point two places away from the percent sign and multiplying.

 

25% of 18 = .25(18) = 4.5, or 4 1/2 inches

 

Hope this helps!
