521Make the denominators the same.
57 =
1521 Number of cupcakes that Eva sold in the morning = 15 u
Number of cupcakes that Eva sold in the evening = 5 u
Number of more cupcakes that Eva sold in the morning than in the evening
= 15 u - 5 u
= 10 u
10 u = 90
1 u = 90 ÷ 10 = 9
Total number of cupcakes that Eva made
= 21 u
= 21 x 9
= 189
