5x4 =
20 u |
1x4 =
4 u |
6x4 =
24 u |
The number of other muffins remains unchanged. Make the number of other muffins the same. LCM of 4 and 1 is 4.
Number of more blueberry muffins baked
= 20 u - 3 u
= 17 u
17 u = 85
1 u = 85 ÷ 17 = 5
Number of muffins that Justin baked at first
= 7 u
= 7 x 5
= 35
Answer(s): 35
