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

We add up all the fractions together.

1/10 + 1/4 + 1/5 + 2/15. LCM of 10, 4, 5 and 15 is 60.

= 6 + 15 + 12 + 8
_________________ = (6 + 15 + 12 + 8) / 60
60

= 41 / 60
