Kylie jarred 12 liters of jam after 2 days. How many days does Kylie need to spend making
atroni [7]
Since it requires 2 days to jar 12 liters of jam, if we want to find out how many days it takes to jar 48 liters, we divide 48 by 12 and get 4.
Then we multiply 4 by 2 and get 8 days. It took 8 days to fill 48 liters of jam.
12/2 = 48/x

12x = 96

x = 8
