Answer:
280 cookies
Step-by-step explanation:
<em>Since, Gavin bakes 70 cookies in an hour that means it is it rate:</em>
<em>70 : 1 or 70/1</em>
<u><em>To Find:</em></u>
<em>How many cookies can he bake in 4 hour</em>
<u><em>Solve:</em></u>
<em>Since in 1 Hour ⇒ 70 cookies</em>
<em>then in 4 Hour ⇒ 70 × 4 = 280</em>
<em />
<em>Now let make a proportion</em>
<em>proportion - an equation in which two ratios are set equal to each other. </em>
<em />
70 × 4 = 280
1 × 280 = 280
280 = 280
<em>Hence, Gavin can bake 280 cookie in 4 hour.</em>
