Answer 2

9-7 7/8 =

To subtract a mixed number like 7 7/8 from 9, we need to first convert the mixed number to an improper fraction:

7 7/8 = (8 * 7 + 7) / 8 = 63/8

Now we can subtract:

9 - 63/8

To subtract fractions with different denominators, we need to find a common denominator. The smallest common multiple of 8 and 1 is 8, so we can convert 9 to an equivalent fraction with a denominator of 8:

9 = 9/1 = (9/1) * (8/8) = 72/8

Now we can subtract the fractions:

72/8 - 63/8 = (72 - 63) / 8 = 9/8

Therefore, 9-7 7/8 = 9/1 - 7 7/8 = 9/1 - 63/8 = 9/1 - 63/8 = 9/1 - 7.875 = 1.125.
