Question

You have a summer job mowing lawns. You mow 3 lawns in 5 hours. How long will it

take to mow 9 lawns. Explain your thinking.

Answer 1

it would take 15 hours

Explanation:

If we know that it would take 5 hours to mow 3 lawns, then we can assume that this ratio will stay the same and multiply this by 3, making it 9 lawns in 15 hours

Answer 2

15 hours

Explanation:

2 ways to do this

1- I know that 3 x 3 is 9 hours which will leads to these equations

3 x 3 = 9

5 x 3 = 15

2- Find out how long it takes for one lawn

5/3 = 1.6666...

1.6666.... x 9 =15

I hope Im correct!
