35 of the total number of tarts. After baking another 12 cherry tarts, the number of cherry tarts became
34 of the total number of tarts. How many tarts did she bake at first?

2 u |
4x2 =
8 u |
The number of other tarts remains unchanged. Make the number of other tarts the same. LCM of 2 and 1 is 2.
Number of more cherry tarts baked
= 6 u - 3 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of tarts that Zane baked at first
= 5 u
= 5 x 4
= 20
Answer(s): 20
