All together they peeled 20
J:jacob
G:grandma
4J=G. Since she peeled 4 times as he did
4J=16
J=4
So jacob peeled 4 potatoes
All in all:J+G
4+16=20
Answer:
16 times
Step-by-step explanation:
This problem is solved by ratio. Since the ratio of 28 out of 25 times is 4:5, he has to catch the ball 4:5 or 4 of 5 times. You multiply both 5 and 4 by 4, because that's how many times he's gonna catch it. 4 x 4 = 16, so the answer is 16 times.
12125-10100 = 2025 total loses
2025/5 = 405 losses per year average
