1. income to expenditure 
2. income to savings 
3. savings to expenditure.

Answer 1

Given:

Income = ₹ 45000

Expenditure = ₹ 31500

Savings = $$45000 - 31500 = \text{₹ } 13500$$

i. Income to expenditure: $$\frac{45000}{31500} = \frac{450}{315} = \frac{10}{7} = 10 : 7$$

ii. Income to savings: $$\frac{45000}{13500} = \frac{450}{135} = \frac{10}{3} = 10 : 3$$

iii. Savings to expenditure: $$\frac{13500}{31500} = \frac{135}{315} = \frac{3}{7} = 3 : 7$$
