Question

Jaime Bailey is chair of a department at a college. Jaime has a budget in which
1.4 of the money is for​ photocopying, 2/5 of the money is for​ computer-related expenses, and the rest of the money is for student tutors in the foreign languages lab. What fraction of​ Jaime's budget is for student​ tutors?

Answer 1

Answer:

Step-by-step explanation:

7/20

Represent the total budget amount by b.

Then from this b, subtract b/4 and then from the result subtract 2/5:

b - b/4 = (3/4)b; now from this (3/4)b subtract (2/5)b:

Converting these proper fractions to decimal fractions, we get:

0.75b - 0.40b = 0.35b

This tells us that 35/100, or 7/20, of Jaime's budget is for tutors.
