Answer 1

To find the ratio of his monthly salary to his expenditure, we first need to calculate both values.

Monthly salary: 480 naira
Monthly expenditure: 390 naira

Now we can find the ratio by dividing the monthly salary by the expenditure:

Ratio = Monthly salary / Monthly expenditure
Ratio = 480 / 390
Ratio = 1.23

Therefore, the ratio of his monthly salary to his expenditure is 1.23:1.
