Ian and Min share some coins.
27 of Ian's coins is equal to
215 of Min's coins. Given that Ian has 24 coins less than Min, how many coins do they have altogether?
27 of Ian's coins = 215 of Min's coins
Number of Ian's coins = 7 u
Number of Min's coins = 15 u
Number of coins that Ian has less than Min
= 15 u - 7 u
= 8 u
8 u = 24
1 u = 24 ÷ 8 = 3
Total number of coins
= 7 u + 15 u
= 22 u
= 22 x 3
= 66
Answer(s): 66
