Question

1. Andy, Brian and Charlie share $72 in the ratio 2:3:4 Work out how much Brian receives.

Answer 1

Відповідь:Brian-24$.

Покрокове пояснення:

Suppose that the coefficient of proportionality = x, then Andy-2x, Brian-3x, Charlie-4x.

2x+3x+4x=72

9x=72

x=8-the coefficient of proportionality.

1)8•3=24($)-Brian.

Answer 2

To find out how much Brian receives, you first need to determine the total number of parts in the ratio (2:3:4) and then divide the total amount ($72) into those parts.

1. Calculate the total number of parts in the ratio 2:3:4: 2 + 3 + 4 = 9 parts

2. Divide the total amount ($72) by the total number of parts (9) to find the value of one part: $72 / 9 = $8 per part

3. Since Brian's share corresponds to 3 parts in the ratio, you can calculate how much Brian receives by multiplying the value of one part by 3: $8/part * 3 parts = $24

Brian receives $24.
