Answer:
12
Step-by-step explanation:
1/3 of 12 = 4
1/4 of 12 = 3
4 is 1 more than 3.
The number is 12.
_____
If this does not immediately come to mind, you can solve for the number, x:
x/3 -x/4 = 1 . . . . the difference between 1/3 of x and 1/4 of x is 1
x/12 = 1 . . . . . . . collect terms: (1/3 -1/4 = 4/12 -3/12 = 1/12)
x = 12 . . . . . . . . multiply by 12
The answer is 30%.... because 50/65 is .3
X + y = 12
x - y = 4
-----------------add
2x = 16
x = 8
x - y = 4
8 - y = 4
y = 4
answer
two numbers: 8 and 4
doule check
sum = 8 + 4 = 12
difference = 8 - 4 = 4
