State two numbers such that the grader number is 75% more than the lesser number
Marianna [84]
75% is equal to 3/4. So the easiest way to do this is to make the smaller number a multiple of 4. Let's say the smaller number is 8. To find the larger number, you must take 75% of 8 and then add it to 8. 1/4 of 8 equals 8 divided by 4, which is 2. Therefore, 3/4 of 8 is 6. 8 + 6 = 14. 

Thus, your two numbers could be 8 and 14.
