Colin spends 1/3 of his wages on rent and 1/4 on food. If he makes £636 per week, how much money does he have left?

uysha [10]

Answer:

£265

Step-by-step explanation:

Total fraction of money spent= $\frac{1}{3} +\frac{1}{4}$

= $\frac{7}{12}$

Actual money spent = $\frac{7}{12}$ * £636

= £371

Money he has left = £(636 - 371)

= £265
