Question

From a sample tray, 4 of the last 10 cake samples chosen were strawberry. Based on past data, of the next 20 samples taken, how many should you expect to be pieces of strawberry cake?

Answer 1

8 because what ever you do to one number you must do to the other
4x2=8 10x2=20

Answer 2

8 out of 20 should be strawberry

Explanation:

4 out of 10 were strawberry so

20 ÷ 10 = 2

2*4=8
