Answer:
Step-by-step explanation:
The total monthly budget is assumed to be 1.
He will use a quarter of his income to pay his rent. It means that the amount of his income that he will use to pay rent is 1/4.
He will use the tenth to the grocery store. It means that the amount he will use at the grocery store is 1/10.
three tenths will be used to buy new furniture. It means that the amount that would be used to buy new furniture is 3/10
Total amount to be spent is
1/4 + 1/10 + 3/10 = 9/20
If he will he deposit the rest in the bank, then the fraction of his budget that he will deposit in the bank is
1 - 9/10 = 1/10
