Math percentage and fraction question

Question

Kyle has .

He gives  of the money to his sister.

He then shares the remaining money in the ratio  and gives the lowest amount to his brother.

He keeps  of what remains thereafter, and gives the rest to his mum.

Work out the amount each person gets.

Answer 1

Hi Zaina,

I’ll assume that 25 means 25% in the question.

Kyle’s sister gets 350 * 25% = $87.50. This leaves 350 - 87.50 = 262.50.

The ratio 3:4 means that his brother gets 3 / (3+4) = 3/ 7 of the 262.50 = $112.50. This leaves 262.50 - 112.50 = 150.

Kyle keeps 150 * 30% = $45.

That leaves 150 - 45 = $105 for his mum.

Please let me know if I can be more helpful, thanks!
