45 of the remainder to Winnie. How many stamps had he left?
Fraction of the stamps left after giving to Carl
= 1 -
58 =
38 Fraction of the remaining stamps left after giving to Winnie
= 1 -
45 =
15
Fraction of the stamps left after giving to Carl and Winnie
= 38 x 15
= 340
Total number of stamps = 40 u
40 u = 400
1 u = 400 ÷ 40 = 10
Number of stamps left
= 3 u
= 3 x 10
= 30
