Favorite Answer

Ok first calulate how mush milk has been used

3 x 700 = 2100 ( for the children

500 mml for the wife

2100 + 500 = 2600 already use

what is left is 3000- 2600 = 400 mls for the husband

Answer 2

As we are dividing up a quantity in litres we should convert to millilitres.

So, 3 litres = 3000ml

Children --> 3 x 700ml = 2100ml

Wife --> 500ml

Children + Wife --> 2600ml

The mans gets 400ml

Answer 3

3l=3000 ml 1/2l=500ml

so the man gets 3000-3*700-500=30000-2100-500=400ml

Answer 4

milk LEFT OFR MAN = 3 -1/2 - 3* .7 = 3-0.5 -2.1

= 0.4 literOR 400 ml ANSWER
