Peter and Opal share some coins.
34 of Peter's coins is equal to
37 of Opal's coins. Given that Peter has 18 coins less than Opal, how many coins do they have altogether?
34 of Peter's coins = 37 of Opal's coins
Number of Peter's coins = 4 u
Number of Opal's coins = 7 u
Number of coins that Peter has less than Opal
= 7 u - 4 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Total number of coins
= 4 u + 7 u
= 11 u
= 11 x 6
= 66
Answer(s): 66
