Answer: x = 6
========================================================
Step-by-step explanation:
The ratio 2:3:4 scales up to 2x:3x:4x after multiplying all three parts by x.
Their sum is 54, so we can say 2x+3x+4x = 54
Solve for x
2x+3x+4x = 54
9x = 54
x = 54/9
x = 6
------------------
Extra info:
if x = 6, then,
- 2x = 2*6 = 12
- 3x = 3*6 = 18
- 4x = 4*6 = 24
Then notice how 2x+3x+4x = 12+18+24 = 54 to help confirm the answer
Also note how 12:18:24 reduces to 2:3:4 after dividing all three parts by the GCF 6.
