Answer 2

??

Answer 3

Can you please explain me how you solve this problem>?

Answer 4

OK well you have an average of 1.24 at the end. Made up of a combo of 1.20 and 1.40.

forget the context and just look at 20 ,24 and 40

4/20 = 1/5. That's how I got it

Answer 5

that it?

Answer 6

well that gives you the amount used of each in a ratio. So for every five litres of orange use one of prune. So the first 6 litres is obvious use 5 orange and 1 prune. Then use 10/6 litres and 2/6 litres for the next 2 litres.

So your answers are 46/6 litres of orange and 8/6 litres of prune.

Answer 7

Answer 8

Answer 9

Uhh haven't done this for a while so not sure of the approved method I just sort of work it out. Maybe if you do the Lowest common multiple of 1.20 1.24 and 1.40. Then do 8 divided by that.

Answer 10

In fact I don't even know if that would work. Not sure how I can make it any easier. That's the way I'd do it sorry

Answer 11
