| After |
4x5 =
20 u |
1x5 =
5 u |
5x5 =
25 u |
The number of other muffins remains unchanged. Make the number of other muffins the same. LCM of 5 and 1 is 5.
Number of more cherry muffins baked
= 20 u - 3 u
= 17 u
17 u = 119
1 u = 119 ÷ 17 = 7
Number of muffins that Mark baked at first
= 8 u
= 8 x 7
= 56
Answer(s): 56
