film animator can draw 4 sketches in 45 minutes. Write and solve a proportion to find how many sketches the film animator can draw in 3 hours. If the film animator continues to draw at the same rate, about how many drawings can be completed in 7 hours Explain.

The film animator can draw 16 sketches in 3 hours

The film animator can draw 37 1/3 sketches in 7 hours

Step-by-step explanation:

4 sketches = 45 minutes

3 hours = 180 minutes

x sketches = 180 minutes

4 : 45 = x : 180

4 / 45 = x / 180

Cross product

4*180 = 45 * x

720 = 45x

x = 720 / 45

= 16

The film animator can draw 16 sketches in 3 hours

how many drawings can be completed in 7 hours ?

7 hours = 420 minutes

x sketches = 420 minutes

4 : 45 = x : 420

4 / 45 = x / 420

Cross product

4*420 = 45*x

1680 = 45x

x = 1680 / 45

= 37 15/45

= 37 1/3 sketches

The film animator can draw 37 1/3 sketches in 7 hours
