Question

For x = 3/4 and y = -9/8, Insert a rational number between (1) x^-1 and y^-1​

Answer 1

Answer:

5/9.

Step-by-step explanation:

(3/4)^-1 = 4/3

(-9/8)^-1 = -8/9

Equal the denominator -

4/3 × 3/3 = 12/9

Rational numbers between 12/9 and -8/9: -7/9, -6/9, -5/9, -4/9, -3/9, -2/9, -1/9, 0/9, 1/9, 2/9, 3/9, 4/9, 5/9, 6/9, 7/9, 8/9, 9/9, 10/9, 11/9, 12/9.

Yo can write anyone rational number.

Answer 2

Answer:

hope it will help you

Step-by-step explanation:

x=3/4 so x^-1=(3/4)^-1

y=-9/8 so y^-1=(9/8)^-1

i.e.

-3×8/-4×8=-24/-32=24/32

similarly to make the denominator same

-9×4/-8×4=-36/-32=36/32

so between 24/32 and 36/32 choose any number.

like 25/32,28/32,35/32 such..
