Cheese
Sold : left
3/7 : 4/7
Raspberry
Sold : left
2/5 : 3/5
Given left
8/11
Meant
Cheese left = 8u
Raspberry left = 3u
Total left = 11u
Since cheese left 8u, made cheese left = 8/14
Cheese
Sold : left
3/7 : 4/7 all multiple 2
6/14 : 8/14
So, total for cheese= 14u
And since Raspberry left = 3u
So Cheese left = 3/5
Total for raspberry= 5u
Total muffins= 14u+5u= 19u
Total sold for
Cheese= 6u
Raspberry= 2u
Total sold = 8u
Fraction= 8u/19u = 8/19
