The number of banana shortbreads Vincent baked was
38 of the total number of shortbreads. After baking another 110 banana shortbreads, the number of banana shortbreads became
56 of the total number of shortbreads. How many shortbreads did she bake at first?

5x5 =

6x5 =
30 u |
The number of other shortbreads remains unchanged. Make the number of other shortbreads the same. LCM of 5 and 1 is 5.
Number of more banana shortbreads baked
= 25 u - 3 u
= 22 u
22 u = 110
1 u = 110 ÷ 22 = 5
Number of shortbreads that Vincent baked at first
= 8 u
= 8 x 5
= 40
Answer(s): 40
