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
