let the required number be x.
According to the question,
3/5 + x × 5/7 = 9/4
=> 3/5 + 5x/7 = 9/4
=> 5x/7 = 9/4 - 3/5
=> 5x/7 = (45 - 12)/20
=> 5x/7 = 33/20
=> x = 33/20 × 7/5
hence the required number is,
x = 231/100

Answer:
3/5 + x + 5/7 = 9/14
3/5 + 5x/7 = 9/14
LCM of 3,7 =35
21 +25x/35 =9/14/
14 (21 + 25x) =9(35)
294 +350 = 315
294 - 315 + 350x
21 + 350
21 = 350
x = 21/ 50
x = 3/50
The number is 3/50 answer
