Left
Banana muffins: 5/8 = 10/16
Walnut muffins: 1/5 = 5/25
(16+25)u = 164
41u = 164
u = 4
Number of banana muffins that were given away by Mrs Tan = (1610)u = 6u = 6x4 = 24.
2)Belle had $48 more than Aiden. Aiden spent 7/8 of his money and Belle spent 4/7 of her money. In the end, Aiden had 1/4 as much money as Belle. Find the amount of money Aiden had at the end.
Left
Aiden: 1/8 = 3/24
Belle: 3/7 = 12/28
(2824)u=48
4u=48
u = 12
Amount of money that Aiden had at the end: 3u = 3x12 = $36
