4x4 =

1x4 =
4 u |
5x4 =
20 u |
The number of other croissants remains unchanged. Make the number of other croissants the same. LCM of 4 and 1 is 4.
Number of more strawberry croissants baked
= 16 u - 3 u
= 13 u
13 u = 91
1 u = 91 ÷ 13 = 7
Number of croissants that David baked at first
= 7 u
= 7 x 7
= 49
Answer(s): 49
