Harry and Wendy share some coins.
47 of Harry's coins is equal to
411 of Wendy's coins. Given that Wendy has 12 coins more than Harry, how many coins do they have altogether?
47 of Harry's coins = 411 of Wendy's coins
Number of Harry's coins = 7 u
Number of Wendy's coins = 11 u
Number of coins that Wendy has more than Harry
= 11 u - 7 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Total number of coins
= 7 u + 11 u
= 18 u
= 18 x 3
= 54
Answer(s): 54
