hi all, this question is actually in one of the exam practise papers for my younger brother who's only 9. I don't know if i should be worried but i came up with the answer (320) using a 6-step long algebraic method.
As i am tutoring him, do any of you guys know an easier, simpler, way to solve it so i can help him understand better? He hasn't learnt algebra yet.
Here's the question:
"After Denis spent $160 of his pocket money on food, and 3/4 of the remaining money to pay his mobile phone bill, he had 1/8 of his total pocket money left. How much pocket money did Denis have at first?"
Thank you so much! Also just out of curiosity, does anyone else think this maths problem isn't so easy for a 9 year old? (or am i just a little daft?)
