Hey mate.... Here is your answer✌️
=>Since a rational number is the ratio between two whole numbers,
=>let a/b be the rational number that is added to -7/4 to get 3/7, so that:
=>-21/4+a/b= 3/7
=>Add the fractions, using the common denominator 4b :
=>4a−21b/4b=3/7
=>7(4a−21b)=12b
=>28a−147b=12b
=>28a=159b
=>a/b=159/28
☺️Because 159 is not divisible by either 2 or 7 (the prime factors of 28),
☺️The numerator and denominator are mutually prime and we cannot simplify the rational number 159/28.

let the required number be 3x
-7/3+3x=3/7
3x=3/7+7/3
3x=9+49/21
3x=58/21
x=58/63
-7/3+3x=3/7
3x=3/7+7/3
3x=9+49/21
3x=58/21
x=58/63
