38 of the total number of croissants. After baking another 34 cranberry croissants, the number of cranberry croissants became
45 of the total number of croissants. How many croissants did she bake at first?

4x5 =

1x5 =
5 u |
5x5 =
25 u |
The number of other croissants remains unchanged. Make the number of other croissants the same. LCM of 5 and 1 is 5.
Number of more cranberry croissants baked
= 20 u - 3 u
= 17 u
17 u = 34
1 u = 34 ÷ 17 = 2
Number of croissants that Bryan baked at first
= 8 u
= 8 x 2
= 16
Answer(s): 16
