= 1 -
25 =
35 Fraction of croissants sold in the evening
=
49 x
35=
415Make the denominators the same.
25 =
615 Number of croissants that Xuan sold in the afternoon = 6 u
Number of croissants that Xuan sold in the evening = 4 u
Number of more croissants that Xuan sold in the afternoon than in the evening
= 6 u - 4 u
= 2 u
2 u = 20
1 u = 20 ÷ 2 = 10
Total number of croissants that Xuan made
= 15 u
= 15 x 10
= 150
Answer(s): 150
