Plz gyz ineed the calculation

a man spends 1/5on his yearly income on rent and taxes 1/2 on household expenses and 1/10 on other expanses. he saves the remainder. what fractions of his income does he save

Step-by-step explanation:

so he spends : 1/5 , 1/2 , 1/10common denominator of 10

1/5 + 1/2 + 1/10 = 2/10 + 5/10 + 1/10 = 8/10 = 4/5

so he spends 4/5 of his income.

that means he saves : 1 - 4/5 = 5/5 - 4/5 = 1/5 <==
