Question

1 litre take 375 millilitres how many millilitres left

Answer 1

You need to convert them both to the same unit which will be millilitres. There are 1000 millilitres in 1 litre so it's 1000 - 375 which is 625 millilitres

Answer 2

From litre to ml is x1000
1 L
10 dL
100 cL
1000 mL

1000 mL - 375 mL = 625 mL
