Question

What rational number should be added to -5 /11 to get -7/8 ​

Answer 1

Answer:

-7/8-(-5/11)

= -7/8+5/11

= -77+40/88

= -37/88

Answer 2

Step by Step solution:

Let the rational no. be x

-5/11 + x = (-7/8)

x = (-7/8) + (5/11)

Now we take the LCM of 8 and 11 to make denominators equal :

LCM of 8 and 11 is 88.

x = (-7/8) + ( 5/11)

x = -77+40/88

x = (-37/88)
