Question 4

First convert the litres.
Eva =1/4 of a litre is 0.25 L
Mo=0.3
Whitney= 1/10 of a litre is 0.1
0.3+0.1=0.4

Then do 0.25+0.3+0.4
0.25+0.3+0.4=0.25+0.30+0.40
0.25+0.30+0.40=0.25+0.70
0.25+0.70=0.95

Question:4
Eva drinks a quarter of a litre of water.
Mo drinks 0.3 litres of water.
Whitney drinks a tenth of a litre more water than Mo.

How much water do Eva, Mo and Whitney drink altogether?

I know I got question number 4 before wrong but now I re did it

1. amuhib Post author

Tamanna,
Very good attempt.

You have four numbers in your number sentence. Can you say who each number relates to.

E.g:
Eva –
Mo –
Whitney –

Try again and write in a number sentence.
