Question

Mito bakes biscuits. he uses 1/4 cup of flour to coat the countertop and the rolling pin. He also uses 2 1/2 cups of flour for each batch of biscuits he bakes. If he uses 7 3/4 cups of flour in all, how many batches of biscuits does he bake? Write and solve an equation

Answer 1

Answer:

Mito can bake 3 batches of cookies.

The amount of flour used to bake cookies   = Total flour used - Amount of  flour  used to coven counter top.

Step-by-step explanation:

Here, the amount of flour used to coat counter top and rolling pin  = 1/4 cup

1/4 cup = 0.25 cup

Now, the amount of cup used to bake 1 batch of cookies  = 2 1/2 cup

Now, 2 1/2 cup  = ( 2 + 1/2 )cup = 2 + 0.5  = 2.5 cup

So, 1 batch of cookies =  2.5 cup

Total amount of flour used  =  7 3/4 cups

Now, 7 3/4 cup  = (7 +  3/4) cup  = 7 +  0.75 = 7.75 cups

The actual amount of flour used to bake cookies

= Total flour used - Amount of  flour  used to coven counter top.

 = 7.75 cup  - 0.25 cup = 7.5 cup

Now, the number of batches baked with 7.5 cup $= \frac{\textrm{Total amount of flour used in baking}}{\textrm{Flour used in 1 batch}}$

$= \frac{7.5}{2.5} = 3$

or,  the number of batches baked with 7.5 cup  is 3 batches.

Hence, Mito can bake 3 batches of cookies.
