Question

A baby weighs 8 pounds 10 ounces. If her weight doubles in 6 months, how much will she weigh in 6 months?

Answer 1

If you double the amount it would be 17 pounds because every 16 ounces would equal a pound.
So your answer would be 17 pounds and 4 ounces

Answer 2

She will weigh 17 pounds and 4 ounces because 8 * 2 = 16, and 10 * 2 = 20. there are 16 ounces in a cup, so you need to add 1 to 16, and 20 - 16 = 4.

 So, She weighs 17 pounds and 4 ounces in 6 months.
