Bob grew a total of 6 inches this year, which is 3 more inches than he grew last year. What is the average number of inches he grew per mont

Bob grew a total of 6 inches this year. What is the average number of inches he grew per month this year?

First of all, the 3 inches Bob grew last year are not relevant to this problem (although they may be relevant to him).

There are 12 months in a year, so the average number of inches he grew per month would be the total (6) divided by the months (12)

= 0.5 inches per month.

The 3 inches last year isn't relavent to the question, because the question is about this year. Let's cross that right out so we don't get confused.

"Bob grew a total of 6 inches this year, which is 3 more inches than he grew last year. What is the average number of inches he grew per month this year?"

"Bob grew a total of 6 inches this year. What is the average number of inches he grew per month this year?"

There is 12 months in a year, so our answer is 6/12.

6/12 can be simplifed to 1/2

 

So the average growth per month is 1/2 inches.

Thanks Ninja and Kitty,

You both give superb answers every time.  

I will admit that Ninja took the edge this time but your answer was really good too Kitty.

Thank you.
