Answer 1

Answer:

-13/60.

Step-by-step explanation:

2/3 + -4/5 + 7/15 - 11/20

Take GCD, make the denominators equal and then add the fractions:

$\frac{2(20) - 4(12) + 7(4) - 11(3)}{60} \\ \frac{40 - 48 + 28 - 33}{60} \\ = \frac{68 - 81}{60} \\ = \frac{ - 13}{60}$

Answer 2

(2/3 + -4/5 + 7/15 + -11/20) = -13/60
