Answer 2

To solve the expression 23.75 - 8 2/3 + 6 5/6, we need to convert all the numbers to a common format. Let's convert the mixed numbers to improper fractions first:

8 2/3 = (8 * 3 + 2) / 3 = 26/3 6 5/6 = (6 * 6 + 5) / 6 = 41/6

Now we can perform the calculation:

23.75 - 26/3 + 41/6

To add or subtract fractions, we need a common denominator. The common denominator for 3 and 6 is 6:

23.75 - (26/3 * 2/2) + (41/6 * 1/1) 23.75 - 52/6 + 41/6

Now that we have the same denominator, we can combine the fractions:

23.75 - (52 + 41) / 6 23.75 - 93/6

To subtract the fractions, we also need a common denominator:

(23.75 * 6/6) - 93/6 142.5/6 - 93/6

Now we can subtract the fractions:

(142.5 - 93) / 6 49.5/6
