Question

what should be added to -5/9 to get the reciprocal of -4/5​

Answer 1

Answer:

we should add -25/36

Step-by-step explanation:

we should get the reciprocal of -4/5 , means we should get -5/4.

let the number to be added to -5/9 be x  to get -5/4.

so -5/9 + x = -5/4

    x= -5/4 - (-5/9)

    x= -5/4 + 5/9

    x=  (-45+20)/36

    x= -25/36

Answer 2

Answer:

25/36

Step-by-step explanation:

-5/ 9 + x = reciprocal of -4/5 = -5/4

-5/9+ 5/ 4 = -20/36 + 45/ 36

= 45-20/36
