Question

If $2$cups of the $1$quart bottle of water was taken away then how many ounces were left?

Answer 1

Hint: Ounce is the unit of weight and is defined as the one sixteenth of the pound whereas, the quart is the unit of liquid which is equal to the quarter or the one fourth part of the substance. Here we will use the correlation between the ounce and quart and will find the required value.

Complete step by step answer:
Quarts is expressed as the unit of liquid which is equal to the four cups in respect to the US (United states) standard. We will use $1$ quart equal to $4$cups. Place the values in the given number of cups and will find the required value.
$4$cups $ = 1$quarts
Also, $8$ounces $ = 1$cup … From (A)
Therefore, finding the correlation –
$1$quarts $ = 4$cups
From equation (A)
$1$quarts $ = 4 \times 8$ounces
Simplify the above equation-
$1$quarts $ = 32$ounces
If we take $2$cups or $16$ounces then $16$ounces will remain.
This is the required solution.

Note: Remember the difference between words quarter and quarts. Quarter means the one of four equal parts into which something is divisible. Simply it is one fourth of the total. Remember the concepts and apply accordingly. You should remember the relation between the two units as it is the base of the solutions.
