Question

What rational no should be subtracted from -2/3 to get -5/6?​ step by step​

Answer 1

Answer:

-1/6

Step-by-step explanation:

Let the no. to be subtracted from -2/3 to get -5/6 be x.

So, -2/3 - x = -5/6

∴ x = -5/6 + 2/3          (Signs change to their inverse while switching sides in an equation)

=> -5/6 + 4/6               (Changing their denominators to 3 and 6's LCM which is 6)

=> (-5 + 4)/6

=> -1/6

Thus, -1/6 is the number to be subtracted from -2/3 to get -5/6.
