Question

If 1 litre = 1000ml, then 4/5 of a litre = _____​

Answer 1

800ml.

Explanation:

If 1 litre = 1000 ml, then

`\small\sf{\quad(4)/(5) \: of \: a \: litre}`

`: \implies\small\sf{(4)/(5) \: of \: 1000}`

`: \implies\small\sf{(4)/(5) * 1000}`

`: \implies\small\sf{(4 * 1000)/(2)}`

`: \implies\small\sf{\cancel{(4000)/(5)}}`

`: \implies\small{\sf{800 \: ml}}`

∴ The answer is 800 ml.
