Answer:
Part #1: 13/15
Part #2: 11/45
Part #3: 23/45
Step-by-step explanation:
Part #1: So add the total amount of coins: 4 + 7 + 12 + 22 = 45
Since the only coins that are at most $1 are: The $1 coins, 50 cent coins, and the 20 cent coins. That is a total of 7 + 12 + 20 = 39
39/45
13/15
Answer: 13/15
Part #2: Since the only coins that are $1 or $2: The $1 coins and the $2 coins. That is a total of 4 + 7 = 11
11/45
Answer: 11/45
Part #3: Since the only coins that are at least 50 cents: The $1 coins and the $2 coins and the 50 cent coins. That is a total of 4 + 7 + 12 = 23
23/45
Answer: 23/45
If Jeff is x years old, Ben is x - 9 years old.
Ten years later, Jeff would be x + 10 years old and Ben would be (x - 9) + 10 years old.
x + 10 + (x - 9) + 10 = 67
2x + 11 = 67
2x = 56
x = 28
Jeff is 28 right now and Ben is 19 right now.
