3x/5=2x/7+44
3x/5-2x/7=44
=21x/35-10x/35=44
11x/35=44
x=44x35/11
=4x35
x=140

Let the ration number be x
So,
two-third of x will be = 2/3 x
three-fifth of x = 3/5 x
so,
2/3 x - 3/5 x = 7/4
x (2/3 - 3/5) = 7/4
x (10/15 - 9/15) = 7/4
x ( 1/15) = 7/4
x = 7/4 * 15
x = 105/4
Therefore, rational number is 105/4
So,
two-third of x will be = 2/3 x
three-fifth of x = 3/5 x
so,
2/3 x - 3/5 x = 7/4
x (2/3 - 3/5) = 7/4
x (10/15 - 9/15) = 7/4
x ( 1/15) = 7/4
x = 7/4 * 15
x = 105/4
Therefore, rational number is 105/4
