Find LCM and solve.

Answer 2

Step-by-step explanation:

given that :

sum of two rational numbers= 4/9

given one of the rational number= -9/5

another rational number= 4/9-(-9/5)

=4/9+9/5

LCM of 9,5= 45

=(20+81)/45

=101/45

therefore other number= 101/45

verification:

sum of two numbers=4/9

so sum of 101/45 and -9/5 should be 4/9

lets check it:

=(101/45)+(-9/5)

=101/45 - 9/5

LCM of 5 , 45 is 45

so ( 101-81 )/45

= 20/45

= 4/9

hence ,proved
