The number of vanilla scones Cole baked was
35 of the total number of scones. After baking another 40 vanilla scones, the number of vanilla scones became
45 of the total number of scones. How many scones did she bake at first?

The number of other scones remains unchanged. Make the number of other scones the same. LCM of 2 and 1 is 2.
Number of more vanilla scones baked
= 8 u - 3 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Number of scones that Cole baked at first
= 5 u
= 5 x 8
= 40
Answer(s): 40
