A container has 20 12 cups of pancake mix. A serving uses exactly 2 ) cups.

just olya [345]

Answer:

10 full servings and $\frac{1}{4}$ cups leftover

Step-by-step explanation:

Our container has a total of 20 and a half cups. And each full serving is 2 cups.

So, we divide $\frac{20\frac{1}{2} }{2}$ .

To do this manually, we convert the numerator into an improper fraction: $\frac{\frac{41}{2} }{2}$ .

Now, we multiply the denominators: $\frac{41}{4}$ .

This will give us $10\frac{1}{4}$ servings. So we only have 10 full servings.

There are $\frac{1}{4}$ cups leftover.
