Question

Christina jarred 21 liters of jam after 3 days. How much jam did she jar if she spent 7 days making jam?

Answer 1

Answer:

49 liters

Explanation:

We know that Christina jarred 21 liters of jam in 3 days, so using this ratio, we can calculate the how much jam she jarred after 7 days as follows

$7\text{ days}\times\frac{21\text{ liters}}{\text{ 3 days}}=49\text{ liters}$

Therefore, the answer is 49 liters.
