When full a jug hold 1 1/3 litres. How many times can the jug be completely filled from a 15 litre container?
15/1.333 = 11.25 = 11 times
To find out how many times the jug can be completely filled from a 15 litre container, you need to divide the total capacity of the container by the capacity of the jug.
The total capacity of the 15 litre container is given as 15 litres.
The capacity of the jug is given as 1 1/3 litres. To make our calculation easier, we can convert this mixed fraction to an improper fraction.
1 1/3 can be written as (3/3 + 1/3) = 4/3 litres.
Now, we can divide the total capacity of the container by the capacity of the jug:
15 litres ÷ (4/3) litres
To divide by a fraction, we can multiply by its reciprocal:
15 litres × (3/4)
Now, multiply the numerators together and the denominators together:
(15 × 3) litres / 4 = 45 litres / 4
To simplify the fraction, we divide both the numerator and denominator by their greatest common divisor, which is 1 in this case:
45 litres / 4 = 45/4 litres
So, the jug can be completely filled from the 15 litre container approximately 11 times, with a remainder of 1/4 litre.
