The ratio of monthly income to the savings in a family is 5 : 4 If the savings be $9000, find the income and the expenses.
Savings are 9000 and have the ratio of four so to get one
9000/4=2250
Income is 5 so and 2250 is 1
2250x5=11250
The difference is 11250-9000= 2250 which is the expenses
Income= 11250
Expenses= 2250
Savings= 9000
Income to savings is 11250 to 9000
Simplify by 2250
We get the ratio 5:4
