Question 1.
Mrs. White brings 70 liters of juice to the school picnic. After the picnic, 12 liters of juice are left. How many liters of juice does everyone drink at the picnic? They drink ____ litres of juice at the picnic.

Question 4.
A barrel has 60 liters of rainwater. Jan uses 17 liters to water her flower garden. She uses another 15 liters to water her vegetable garden. How much rainwater is left in the barrel?

subtract the total rainwater and rainwater used to get the rainwater left in the barrel.
X=60-32
X=28
Therefore, 28 litres are left in the barrel.

The number of litres of water container A=17+2=19 ( 2 litres more than container B).
The number of litres Jasmine pours into container B=7
Now we need to calculate the total number of litres in container B. Assume it as X.
add the starting water in container B that is 17 and after adding that is poured extra in the container B.
X=17+7
X=24 litres.
Therefore, there are 24 litres in container B.
