Bought a 25 pound bag of dog food

3⅘ lb

Step-by-step explanation:

(a) Amount eaten

Eaten = 10⅖ + 10⅘

Think of pounds as pies. Each pie has 5 slices.

10⅖ pies = 10 pies + 2 slices = 50 slices + 2 slices = 52 slices

10⅘ pies = 10 pies + 2 slices = 50 slices + 4 slices = 54 slices

Eaten = 52 slices + 54 slices = 106 slices

(b) Amount remaining

Remaining = Original - Eaten

Original = 25 pies = 125 slices

Eaten = 106 slices

Remaining = 125 slices - 106 slices

Remaining = 19 slices Convert slices to pies

Remaining = 15 slices + 4 slices

Remaining = 3 pies + 4 slices Convert to mixed fraction

Remaining = 3⅘ pies Convert pies to pounds

Remaining dog food = 3⅘ lb
