Using proportions, it is found that:

  • Andrew gets R 1850.
  • Each of Brendan and Clair get R 1387.5.

What is a proportion?

A proportion is a fraction of total amount.

In this problem, the total amount divided is R 4625.

For every R4 Andrew gets, both Brendan and Clair gets R3, hence the ratio is 4:3:3, which means that:

  • Andrew gets [tex]\frac{4}{4 + 3 + 3} = \frac{4}{10} = 0.4[/tex] of the total amount.
  • Brendan gets [tex]\frac{3}{4 + 3 + 3} = \frac{3}{10} = 0.3[/tex] of the total amount.
  • Clair gets [tex]\frac{3}{4 + 3 + 3} = \frac{3}{10} = 0.3[/tex] of the total amount.

Then:

[tex]A = 0.4(4625) = 1850[/tex]

[tex]B = C = 0.3(4625) = 1387.5[/tex]

Hence:

  • Andrew gets R 1850.
  • Each of Brendan and Clair get R 1387.5.
