Order of operations with fractions: add, subtract and multiply

Work in order: parentheses, then multiply and divide, then add and subtract. Write a fraction in lowest terms or a whole number.

1. Evaluate: 2/5 + 5/8 + (−1/2) (Write a fraction in lowest terms, or a whole number.)
2. Evaluate: −1/2 + (−3/4) − (−2/3) (Write a fraction in lowest terms, or a whole number.)
3. Evaluate: (1/2 × 1/3) − (−1/8) (Write a fraction in lowest terms, or a whole number.)
4. Evaluate: (−2/5 − (−1/2)) − (−3/8) (Write a fraction in lowest terms, or a whole number.)
5. Evaluate: −7/10 + (−2/5) − 5/6 (Write a fraction in lowest terms, or a whole number.)
6. Evaluate: (1/2 + (−1/2)) + (−1/6) (Write a fraction in lowest terms, or a whole number.)
7. Evaluate: 2/3 − 3/5 − (−1/3) (Write a fraction in lowest terms, or a whole number.)
8. Evaluate: (1/3 × 2/3) + (−3/5) (Write a fraction in lowest terms, or a whole number.)
9. Evaluate: (−1/4 + (−2/5)) − (−1/2) (Write a fraction in lowest terms, or a whole number.)
10. Evaluate: −1/2 + (−3/5) − (−1/2) (Write a fraction in lowest terms, or a whole number.)
11. Evaluate: (−1/3 + 1/5) + 1/5 (Write a fraction in lowest terms, or a whole number.)
12. Evaluate: 7/8 × (−3/4) − (−1/2) (Write a fraction in lowest terms, or a whole number.)
13. Evaluate: (1/2 × (−2/5)) × (−5/6) (Write a fraction in lowest terms, or a whole number.)
14. Evaluate: (−1/3 − 6/7) + (−6/7) (Write a fraction in lowest terms, or a whole number.)
15. Evaluate: −1/2 − 2/7 − (−1/4) (Write a fraction in lowest terms, or a whole number.)
16. Evaluate: (2/3 + 1/2) − (−2/3) (Write a fraction in lowest terms, or a whole number.)
17. Evaluate: 5/8 × 3/5 − (−3/7) (Write a fraction in lowest terms, or a whole number.)
18. Evaluate: (2/3 − (−2/3)) + (−1/2) (Write a fraction in lowest terms, or a whole number.)
19. Evaluate: (−1/7 × (−1/2)) × 3/4 (Write a fraction in lowest terms, or a whole number.)
20. Evaluate: (3/5 × (−2/3)) × (−1/2) (Write a fraction in lowest terms, or a whole number.)
