Question

a jug contains 1 l 800ml water how many 200ml glasses can fill

Answer 1

$1800 \div 200 = 9$

Answer 2

Convert litres to ml:

1 litre = 1000 ml

1ℓ 800 ml = 1000 + 800  = 1800 ml

Find the number of glasses needed:

1 glass = 200 ml

Number of glasses = Total amount of liquid ÷ capacity of a glass

Number of glasses = 1800 ÷ 200 = 9 glasses

Answer: The jug can fill up 9 glasses
