How many 1/2 cups servings are in a package of melted cheese that contain 5 1/4 cups together?

Question

Diving Fractions Question

Answer 1

The question is to determine how many halves are in 5 1/4.

You can easily tell how many halves in 5 but the difficult part may be the 1/4.

Therefore divide. First, change 5 1/4 to improper fraction, so it equals 21/4; second, when you divide by a fraction, such as 1/2, it is equivalent to multiplying by the reciprocal which in this case is 2.

(21/4)(2)= 21/2 OR 10 1/2.

There are 10 1/2 half cup servings of cheese.

 

Answer 2

We want to know how many 1/2 cups make 5 1/4 cups.  To find this out, we divide 5 1/4 by 1/2.

 

 

(5 1/4) / (1/2)

 

 

First, we need to convert the mixed number , 5 1/4,  into an improper fraction.

 

5 1/4 = 21 / 4

 

 

Now we have

 

(21 / 4) / (1 / 2)

 

 

When we divide fractions, we multiply by the reciprocal of the second fraction.

 

(21 / 4) * 2 = 21 / 2 = 10 1/2

 

 

The number of cups must be an integer.  If we have 10 of these 1/2 cup servings, it will be less than the total number of cups together.  So 11 of these 1/2 cup servings are in the package.
