nice maths problem?

2:3 == 2 glue to 3 water

2:3 == 40% glue

(2+3 = 5, 2/5 = .4 == 40%)

40% of 3L = 1.2L

1.2L / .5(can) = 2.4 (can)

Since you cannot buy partial cans:

ANSWER = 3 cans

Good luck!

The ratio of glue to water in the mixture is 2:3

That means that if you divide it up into five parts, two would be glue and three would be water.

That is, 2/5 of the mixture should be glue and 3/5 of the mixture should be water

Can you do the rest of the question yourself now?

if the ratio is 2 parts (glue) to 3 (water), then there are five "parts" in the mixture.

so 3 / 5 = 0.6

a) two parts of glue = 1.2 litres

b) he needs three 1/2 litre cans.

there's no reason to characteristic the two money to the 27. that's flawed good judgment. each and each guy has paid 9, so 3 x 9 = 27 Of the unique 30, the supervisor has 25, the bellboy has 2 and the adult adult males have the different 3

a) 2x +3x = 3

5x = 3 x = .6 2x = 1.2 litres

b) 1.2/.5 = 2.4 cans. I guess he has to buy 3 cans.
