Question

what should be subtracted from -18/5 to get -5/6

Answer 1

Let x be subtracted ...

$\frac{ - 18}{5} - x = \frac{ - 5}{6} \\ \\ - x = \frac{ - 5}{6} + \frac{18}{5} \\ \\ - x = \frac{ - 25 + 108}{30} \\ \\ - x = \frac{83}{30} \\ \\ x = \frac{ - 83}{30}$

Answer 2

Answer:

(-18/5) - x = -5/6

-18/5 + 5/6 = x

(-108+25)/30 = x

-83/30 = x

Therefore, -83/30 should be subtracted from -18/5 to get -5/6.
