6x3 =

1x3 =
3 u |
7x3 =
21 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 vanilla macarons baked
= 18 u - 5 u
= 13 u
13 u = 130
1 u = 130 ÷ 13 = 10
Number of macarons that John baked at first
= 8 u
= 8 x 10
= 80
Answer(s): 80
