Sum of two rational number is minus 3 upon 5 if one of the number is minus 9 upon 20 find the other rational number

Answer»

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)
