Answer:
4). Shade in 6 out of the 10 boxes
5). Shade in 2 parts of the circle
Explanation:
4). (3/10) +(2/10)+(1/10) = 6/10
Since there are 10 boxes, you shade in 6 of them. This is how much of their profits they donated.
5). It says he needs 3/4 of a cup, but he only has 1/4. You have to subtract these fractions to see how much more he needs. (3/4)-(1/4) = 2/4. This means you shade in 2 parts of the circle.
