How many 5 1/4 ounce glasses can be completely filled from a 33 1/2 ounce container of juice?

You need to divide.
We are dividing the mixed numeral 33 1/21 by the mixed numeral 5 1/4.

(33 1/2 ) / (5 1/4) =

The first step is to change the two mixed numerals into improper fractions.
33 1/2 = 67/2, and 5 1/4 = 21/4

= (67/2) / (21/4)

Now we are dividing the fraction 67/2 by the fraction 21/4.
To divide a fraction by a fraction, rewrite the first fraction, change division intro multiplication, and flip the second fraction. To divide 67/2 by 21/4, we multiply 67/2 by 4/21.

= 67/2 * 4/21

To multiply fractions, multiply together the numerators, and multiply together the denominators. 67 * 4 = 268; 2 * 21 = 42

= 268/42

Using a calculator, 268/42 = 6.38095...

You can fill 6 full glasses.

It takes two apples to make an apple pie. If a chef bought nine apples, the last pie
defon

Hey!

-------------------------------------------------

If a chef bought 9 apples and each pie takes 2 apples then all we have to do is divide.

9 / 2 = 4.5

4 full pies can be made with 9 apples.

4 x 2 = 8 (apples were used to make 4 pies.)

9 - 8 = 1 (apple remaining)

If one pie needs 2 apples, subtract.

2 - 1 = 1 (pies the chef needs to make the last one)

-------------------------------------------------

Answer: The last pie would need 1 more apple.
