Question

compare the rational number. -7/8 and 6/-7
​

Answer 1

Step-by-step explanation:

First we write each of the given numbers with positive denominator.

One number = 3/(−4) = {3 * (−1)}/((−4) * (−1)}  = −3/4

The other number = −5/6

Now, we ignore the sign of the numbers and take the rational numbers as 3/4 and 5/6

Now, L.C.M. of 4 and 6 = 12

Therefore, 3/4 = (3 * 3)/(4 * 3) = 9/12

and 5/6 = (5 * 2)/(6 * 2) = 10/12

Now, 9 < 10

=> -9 > -10

=> −9/12 > −10/12

Hence, 3/(−4) > −5/6
