Question

A family spends 1/10 of its annual income for housing, 1/4 for food and clothing,1/5 for general expenses, and 2/15 for entertainment. What fractional part of their income is spent on these items altogether?

Answer 1

41/60 or 68.3%

Explanation:

1/10 + 1/4 + 1/5 + 2/15

common denominater is 120

120/10 = 12

120/4 = 30

120/5 = 24

120/15 = 8

Since all numerators are 1 just add all the numbers together

but multiply 2 by 8

12 + 30 + 24 + 16 = 82

82/120 = 41/60 in simplist terms
