anna made 400 quarts of lemonade. she poured the lemonade into the containers. each container holds 4/7 of a quart. how many containers did anna use
400 / (4/7)
400 * (7/4) = 2800/4 = 700 containers
anna made 400 quarts of lemonade. she poured the lemonade into the containers. each container holds 4/7 of a quart. how many containers did anna use
To find out how many containers Anna used, we need to divide the total amount of lemonade she made (400 quarts) by the capacity of each container (4/7 of a quart).
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of 4/7 is 7/4.
So, the calculation would be:
400 quarts ÷ (4/7 of a quart)
= 400 quarts × (7/4)
= (400 × 7) / 4
= 2800 / 4
= 700 containers
Therefore, Anna used 700 containers of lemonade.
