Question

the sum of two rational number is -13 by 33 . if one of them is -7 by 11 find the other

Answer 1

Let the Other number be X

We know The sum of X and -7/11 is -13/33

hence

-7/11 + X = -13/33

X = -13/33 + 7/11

X= -13/33 +21/33

X= 8/33

Hence the other number is 8/33

Answer 2

Let the required rational no be p/q
given rational no = -7/11
acc to question
p/q + (-7/11) = -13/33
p/q = -13/33 - (-7/11)
p/q = -13/33 + 7/11
p/q = 88/363
p/q = 8/33
