The number of cheese macarons Gabriel baked was
37 of the total number of macarons. After baking another 65 cheese macarons, the number of cheese macarons became
45 of the total number of macarons. How many macarons did she bake at first?

| After |
4x4 =
16 u |
1x4 =
4 u |
5x4 =
20 u |
The number of other macarons remains unchanged. Make the number of other macarons the same. LCM of 4 and 1 is 4.
Number of more cheese macarons baked
= 16 u - 3 u
= 13 u
13 u = 65
1 u = 65 ÷ 13 = 5
Number of macarons that Gabriel baked at first
= 7 u
= 7 x 5
= 35
Answer(s): 35
