We have been given two numbers : -7/9 and 3/7.
To Find:
We neee to find a number(x) which should be added to thrice a rational number -7/9 so that we get 3/7.
Solution:
Let the number be x.
According to question:
x + {3 × (-7/3)} = 3/7
=> x + (-7) = 3/7
=> x - 7 = 3/7
=> x = 3/7 + 7
=> x = (3 + 49)/7 [Taking LCM as 7]
=> x = 52/7
Hence the required number is 52/7.
