Question

User: 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?

a. 41/60
b. 6/41
c. 11/12
d. 1/7

Answer 1

`(1)/(10)+(1)/(4)+(1)/(5)+(2)/(15)= \\ \\ (1 * 6)/(10 * 6)+(1 * 15)/(4 * 15)+(1 * 12)/(5 * 12)+(2 * 4)/(15 * 4)= \\ \\ (6)/(10)+(15)/(60)+(12)/(60)+(8)/(60)= \\ \\ (41)/(60)`

The answer is A.
