Question

Gary took 7 hours to mow 4 lawns, then at the rate, how many lawns could be mowed in 35 hours?

Answer 1

Let's find out!

Explanation:

So, he can mow a lawn in 7/4 hours

So, to find out how many he could do in 35 hours:

`(7x)/(4)=35 \\7x=140\\x=20`

He can mow 20 lawns in 35 hours!

Hope this helps!

Answer 2

Set a proportion. 7h - 4 lawns

35h - x lawns

Now, cross multiply. (35 x 4) / 7= 20

So, he would mow 20 lawns in 35 hours
