28 buckets of water fill a tank when the capacity of each bucket is 13.5 litres . how many buckets will be required to fill the same tank if the capacity of each bucket is 9 litres ?
"capacity of the tank = 28 ã — 13.5 = 378 litres when the capacity of each bucket = 9 litres , then the required no . of buckets = 378 â  „ 9 = 42 answer b"
divide(multiply(13.5, 28), 9)
