25 of the total number of macarons. After baking another 110 banana macarons, the number of banana macarons became
45 of the total number of macarons. How many macarons did she bake at first?

Other macarons |
Total macarons |
| Before |
2 u |
3 u |
5 u |

| After |
4x3 =
12 u |
1x3 =
3 u |
5x3 =
15 u |
The number of other macarons remains unchanged. Make the number of other macarons the same. LCM of 3 and 1 is 3.
Number of more banana macarons baked
= 12 u - 2 u
= 10 u
10 u = 110
1 u = 110 ÷ 10 = 11
Number of macarons that Ken baked at first
= 5 u
= 5 x 11
= 55
Answer(s): 55
