John is cutting a 10 foot long piece of pipe into lengths of 2/3 foot. How many pieces of pipe with this length can he cut?

Question

I am trying to help my 12 year old son with 6th grade math. Can you help us figure out how to work the proble?

Answer 1

10 ÷ 2/3    The pipe is divided into 2/3 foot sections.

10 * 3/2     To divide by a fraction multiply by its inverse

30/2          Multiply

15             Reduce

Answer 2

How many 2/3 's are there in 10 ?

10÷(2/3)=10*(3/2)=30/2=15 pieces of pipe
