Question

Luke can paint 91 portraits in 7 weeks.

Answer 1

Hey!

91 ÷ 7 = 13

So, we know that Luke paints one portrait every week.

13 × 4 = 52

So, Luke paints 52 portraits in 4 weeks.

Answer 2

First, we can calculate the number if portraits he can paint in one week.
We can do this by simply dividing the total portraits by the weeks needed.

91 ÷ 7
=13

Now, to calculate the number of portraits he can paint in 4 weeks, just multiply the total number of paintings he can do in a week by 4.

13 x 4
=52
So the answer is 52 portraits.
