Question

What is -5/6 + 2/7 (fractions)

Answer 1

Answer:

-23/42

Step-by-step explanation:

Least common multiple of 66 and 77 is 4242. Convert -\frac{5}{6}\approx -0.833333333−65≈−0.833333333 and \frac{2}{7}\approx 0.28571428672≈0.285714286 to fractions with denominator 4242.

-\frac{35}{42}+\frac{12}{42}\approx -0.547619048−4235+4212≈−0.547619048

-\frac{35}{42}\approx -0.833333333\frac{12}{42}\approx 0.285714286

\frac{-35+12}{42}\approx -0.54761904842−35+12≈

−4235+4212≈−0.547619048



Since -\frac{35}{42}\approx -0.833333333−4235≈−0.833333333 and \frac{12}{42}\approx 0.2857142864212≈0.285714286 have the same denominator, add them by adding their numerators.

\frac{-35+12}{42}\approx -0.54761904842−35+12≈−0.547619048

42−35+12≈−0.547619048



Add -35−35 and 1212 to get -23−23.

-\frac{23}{42}\approx -0.547619048−4223≈−0.547619048

−4223≈−0.547619048
