Answer:
Step-by-step explanation:
Let the number be x
three-quarters of the number = 3/4 of x = 3x/4
three-fifths of a number = 3/5 0f x = 3x/5
3x/4 - 3x/5 = 9
3x*5/4*5 - 3x*4/5*4 = 9 {making equivalent fractions}
15x/20 - 12x/20 = 9
15x - 12x /20 = 9
3x/20 = 9
x = 9*20/3 = 3 * 20 = 60
The number is 60
