Answer:
The mixed number 5 1/4 is equal to the improper fraction 21/4.
Percent means parts ot of 100
25%=25/100=1/4
ratio is 1:4 or 2:8 or 6:12
Let x represent the larger number.
Let y represent the smaller number.
x-y=4 Given
3x=5y-2 Given
Now we can just substitute; let x=4+y
Substitute 4+y for x in the second equation:
3(4+y)=5y-2
12+3y=5y-2
-2y=-14
y=7
Substitute back (into BOTH equations to double check work).
x, the larger number, is 11
