Question

Janelle can paint 4/5 of a picture in 2/7 of an hour how many can she pain in a full hour

Answer 1

2 4/5 pictures

Explanation:

We can use a ratio to solve

4/5 picture x picture

-------------- = -------------

2/7 hour 1 hour

Using cross products

4/5*1 = 2/7x

Multiply each side by 7/2

4/5 * 7/2 = 7/2 * 2/7 x

28/10 =x

2 8/10=x

2 4/5
