6x5 =
30 u |
1x5 =
5 u |
7x5 =
35 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 blueberry croissants baked
= 30 u - 2 u
= 28 u
28 u = 224
1 u = 224 ÷ 28 = 8
Number of croissants that Ivan baked at first
= 7 u
= 7 x 8
= 56
Answer(s): 56
