7/8-5/6

To subtract fractions, the denominators must be the same. In this case, the common denominator is 24, which is the least common multiple of 8 and 6.

Next, we need to convert both fractions to have the denominator of 24.

For the first fraction, multiply the numerator and denominator by 3: 7/8 = (73)/(83) = 21/24

For the second fraction, multiply the numerator and denominator by 4: 5/6 = (54)/(64) = 20/24

Now, we can subtract: 21/24 - 20/24 = (21-20)/24 = 1/24

Therefore, 7/8 - 5/6 = 1/24.
