Answer:
There are 5 liters in every bucket of water.
Explanation:
OK, so the question is : it took 4 buckets of water to fill a 20-liter tub. how many liters are in each bucket?
We already know how many buckets of water were needed to fill the 20 liter tub. Luckily in our case it's really simple, 4. Which divides into 20 equally and without decimals. All we need to do to is take the amount of liters the tub holds (20) and divide that number by the amount of water buckets used (4). In this case we do 20 ÷ 4. This will show us how many liters each bucket of water holds.
So :
20 ÷ 4 = 5
Therefore your answer is 5 Liters in every bucket of water.
