To find the difference between nine-fourths and one-seventh, you need to subtract one-seventh from nine-fourths.
To subtract fractions, you need to have a common denominator. In this case, the common denominator is 28 (the LCM of 4 and 7).
Converting nine-fourths to twenty-eightths, you multiply both the numerator and denominator by 7. So, nine-fourths equals sixty-three twenty-eighths (63/28).
Now, subtracting one-seventh (4/28) from sixty-three twenty-eighths (63/28), we get the result:
63/28 - 4/28 = 59/28
Hence, the difference between nine-fourths and one-seventh is fifty-nine twenty-eighths (59/28).
