280 cookies
Step-by-step explanation:
Since, Gavin bakes 70 cookies in an hour that means it is it rate:
70 : 1 or 70/1
To Find:
How many cookies can he bake in 4 hour

Since in 1 Hour ⇒ 70 cookies
then in 4 Hour ⇒ 70 × 4 = 280
Now let make a proportion
proportion - an equation in which two ratios are set equal to each other.
[tex]\frac{70}{1}=\frac{280}{4}[/tex]
70 × 4 = 280
1 × 280 = 280
280 = 280
Hence, Gavin can bake 280 cookie in 4 hour.
