Question

the sum the sum of two rational number is minus 8 if one of thenumbers ismine -13.7 ,find the other​

Answer 1

Answer:

The answer is -3/20(The other rational number)

Step-by-step explanation:

To find the other rational number

Step = Let the unknown other rational number be x

And equate the addition of the two rational numbers with their sum

That is,

-9/20 + x = -3/5

x = -3/5 + 9/20

Now take the L.C.M of the denominators[5 and 20]

That is 20

So,

-3/5 X 4/4 and 9/20 X 1/1(To make the denominators equal)

-12/20 and 9/20

Now,

x = -12/20 + 9/20

  = -12 + 9/20

   = -3/20(The other rational number)
