Fraction of apple muffins left
= 1 -
47 =
37Fraction of blueberry muffins left
= 1 -
13 =
23The number of apple muffins and blueberry muffins in the end is the same. Make the numerators the same. LCM of 2 and 3 is 6.
37 of apple muffins =
23 of blueberry muffins
614 of apple muffins =
69 of blueberry muffins
Number of more apple muffins than blueberry muffins at first
= 14 u - 9 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Number of apple muffins that Ivory gave away
= 14 u - 6 u
= 8 u
= 8 x 8
= 64
Answer(s): 64
