6x1 =

1x1 =
1 u |
7x1 =
7 u |
The number of other croissants remains unchanged. Make the number of other croissants the same. LCM of 1 and 1 is 1.
Number of more cherry croissants baked
= 6 u - 4 u
= 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Number of croissants that Bobby baked at first
= 5 u
= 5 x 2
= 10
Answer(s): 10
