Answer:
The flour left with her = 13 1/2 cups
Step-by-step explanation:
Flour in the container = 15 3/4 cups = 63/4
Flour used to make bread = 2 1/4 cups = 9/4
The flour left with her = (63/4) - (9/4)
= (63 - 9)/4
= 54/4 = 27/2
= 13 1/2 cups
OR
The flour left with her = 15 3/4 - 2 1/4
= (15 - 2 ) + (3/4 - 1/4)
= 13 + (2/4)
= 13 + (1/2)
= 13 1/2 cups
