Question

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

Answer 1

Answer:

-5/11 + X = -7/8

X = -7/8 + 5/11

X = (-77 + 40) /88

X= -37/88

Answer 2

let the rational number be X.

$x + \frac{ - 5x}{11} = \frac{ - 7}{8} \\ = \frac{11x + ( - 5x)}{11} = \frac{ - 7}{8} \\ = \frac{6x}{11} = \frac{ - 7}{8} \\ = 6x = \frac{ - 7}{8} \times 11 \\ = 6x = \frac{ - 77}{8}$
