## patbatE21 3 years ago A recipe requires 3 ingredients A, B, C in the volume ratio 2:3:4. If 6 pints of ingredient B are required, how many pints of ingredients A and C are required?

1. Walleye

2A = 3B = 4C

2. Walleye

do you understand my hint?

3. patbatE21

2A = 3(2) = 4C

4. patbatE21

therefore A & C are 2 as well?

5. Walleye

if a= 2 and c =2 then 4 = 6 =8 ?????

6. patbatE21

Ok they aren't equal

7. patbatE21

I only know B=6 and I can use 2(3) to make A but there is no way for C

8. Walleye

4C = 6 solve for C

9. patbatE21

oh

1.5

this is how I would do it: THe ratio for B is 3, but you need 6 pints. This required multiplying by 2. therefore you multiply the A and C portions by 2 as well. So A is 4 pints and C is ?

12. Rogonic

Or 2:3:4 = ? :6: ? look at the pattern.

13. Rogonic

I'm afraid Walleye has misled you a little. It is not true that 2A=3B=4C, though it is a common mistake.

14. patbatE21

So A =4 and C=8

15. Rogonic

Yes
