Question

Keisha’s family drinks 2 quarts of orange juice at breakfast. The children drink 2 pints and 1 cup of orange juice. How much orange juice is left for the adults to drink? Give your answer in pints in cups. Do the children or adults drink more orange juice?

Answer 1

Well, first thing is to convert 2 quarts into pints and cups. We know that 1 quart = 2 pints.

Hence, the family drinks 2 * 2 = 4 pints

The amount the adults drink is the what the family amount that drinks - what the children drink.

4 pints - 2 pints and 1 cup

There are a few different ways you can go from here.

Option 1: convert everything to pints

We know that 1 cup = 0.5 pints

So the children drink 2+0.5 = 2.5 pints

Adults drink 4 - 2.5 = 1.5 pints

1.5 = 1 + 0.5

Since we know that 1 cup = 0.5 pints,

The adults drink 1 pint and 1 cup.

Option 2: convert everything to cups

We know that 1 pint = 2 cups

So the family drinks 4 * 2 = 8 cups

And the children drink 2 * 2 + 1 = 5 cups

The adults drink 8 - 5 = 3 cups

3 = 1 + 2

Since we know that 1 pint = 2 cups,

The adults drink 1 pint and 1 cup.

1 pint and 1 cup < 2 pints and 1 cup

Therefore, the children drink more
