Question

(-1/17) + (. ) =-12/5​

Answer 1

Answer:

-12/5 is answer of your questions

Answer 2

Step-by-step explanation:

Given that :-

(-1/17) + (. ) =-12/5

Let the number in the bracket be X

then

(-1/17)+X=-12/5

=>X=-12/5+1/17

LCM of 5 and 17 =85

=>X=[(-12×17)+(1×5)]/85

=>X=[(-204)+5]/85

=>X=-199/85

The number in the bracket should be -199/85

Check:-

(-1/17)+(-199/85)

=>[(-1×5)+(-199)]/85

=>(-5-199)/85

=>-204/85

=>-12/5

Verified

or you gave like this

(-1/17)+(-12/5)=(-12/5)+(-1/17)

This is Commutative property under addition in rational numbers
