the label on the cordial says "to make 1 litre of fruit juice, use 200 ml of cordial and 800 ml of water"

james uses 250 ml cordial and 850 ml of water.

is james using the correct proportions?

show working to justify answer.

**Ms. Sue**, Sunday, October 7, 2012 at 1:43pmLet x equal the amount of water needed.

200/800 = 250/x

200x = 200,000

x = 1,000 ml

**Anonymous**, Sunday, October 7, 2012 at 2:13pmsince she bought 200g peanuts, that's 4 times as much as she needs for one batch of 20 cookies.

So, multiply all the other amounts by 4 to use up all the nuts and make 80 cookies.
