Which of the following does not have a ratio of 2: 3: 4?

a) {8, 15, 24}
b) {2x, 3x, 4x}
c) {6m2, 9m2, 12m2}

Step-by-step explanation:

In this problem we have a ratio with numbers

so

Let

x------> the first number

y-----> the second number

z-----> the third number

we know that

------> equation A

------> equation B

------> equation C

Verify each case

case A)

Substitute in the equations

therefore

The case A) not have a ratio of

case B)

Substitute in the equations

therefore

The case B) have a ratio of

case C)

Substitute in the equations

therefore

The case C) have a ratio of
