Each month for 7 months, samuel mows 3 lawns. how many mire lawns does he need to mow before he has mowed 29 lawns

Hello! I would love to help!

Okay, let's think. We know that for 7 months, he mowed 3 lawns. Basically, you can picture 7 groups with 3 lawns in each.

Essentially, what the first part of the problem is asking is: What is 3 times 7?

We can do that!

3*7=21

So we now know that he has already mowed 21 lawns. But, we also know that in all, Samuel has to mow 29 lawns. So how do we take away the 21 lawns from the 29 he has to do in all?

Tha Let's subtract!

29-21=8

So, your answer is 8 more lawns!

Hope this helped! Comment if you have any questions!
