45 of the total number of macarons. After baking another 18 cranberry macarons, the number of cranberry macarons became
67 of the total number of macarons. How many macarons did she bake at first?

1x1 =
1 u |
7x1 =
7 u |
The number of other macarons remains unchanged. Make the number of other macarons the same. LCM of 1 and 1 is 1.
Number of more cranberry macarons baked
= 6 u - 4 u
= 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Number of macarons that Zane baked at first
= 5 u
= 5 x 9
= 45
Answer(s): 45
