Question

"A recipe for making 3 dozen muffins required 2.25 cups of flour. At this rate, how many cups of flour are required to make 4 dozen muffins?"

Answer 1

3 cups of flour

Explanation:

2.25/3 = 0.75
so one dozen muffins need 0.75 cups of flour

0.75 * 4 = 3

so 4 dozen muffins need 3 cups of flour

Answer 2

3 cups of flour.

Explanation:

For 3 dozens of muffins we use 2.25 cups of flour. To find out how much flour we need for 4 dozens of muffins, we first need to know how much flour we need for 1 dozen of muffins.

3 dozens of muffins = 2.25 cups of flour

3/3 dozens of muffins = 2.25/3 cups of flour

1 dozen of muffins = 0.75 cups of flour.

Now that we know how much flour we need for one dozen of muffins, we can multiply it by 4 and get our answer.

1*4 dozens of muffins = 0.75*4 cups of flour

4 dozens of muffins = 3 cups of flour.

Hope this helps.
