2) 14
3) 20
4) 35

Answer 1

If a student ate 7 slices of a pizza, it represents 70% of the pizza.

Step-by-step explanation:

If a student ate 7 slices of a pizza, which is 70, we can set up a proportion to find out how many slices represent 100%. Let's say x is the number of slices that represent 100%.

We have the proportion:
x/100 = 7/70
Cross multiplying, we get x = 100 * (7/70) = 10 slices.

Therefore, if a student ate 7 slices, it represents 70% of the pizza.
