none
Let the numbers be 5x and 7x.
Given 5x−157x−15=1017.
Solving, we get, x=9.
So the smaller number is 35.
Two numbers are in the ratio 3:5. If 9 is subtracted from each number, the ratio becomes 12:23. The smaller number is:
Two numbers are in the ratio 3:5. If 9 is subtracted from each, the new numbers are in the ratio 12:23. The smaller number is:
