Question

The ratio of red sweets to sweets that are not red is 2:3

The ratio of green sweets to sweets that are not green is 6:19
Work out the ratio of red sweets to blue sweets to green sweets

I saw an answer but assuming that the total is 50 doesn't make any sense.
I also saw an answer that didn't put any method/calculations. I NEED to put the method there otherwise my teacher will think I cheated and I will not be able answer questions like this in the future.

Answer 1

Extremely sorry if my answer is wrong or doesn't make sense! Also sorry that I couldn't solve it farther, I solved it using sense and haven't made it this far in math!

Explanation:

If red is 2:3 then that means red to green is either 2:2 or 2:1. Same goes with blue.

If green is 6:19 then we can figure out the 2 possibilities for red to green.

First Possibility:

If the red to green ratio is 2:2, then the red to green to blue is 6:6:13 because 6 + 19 - 12 = 13.

Second Possibility:

If the red to green ratio is 2:3, then the red to green to blue ratio is 4:6:15 because 6 + 19 - 10 = 15.
