Apply the definition of subtraction and properties of operations to find the result.
1 over 8 minus 3 over 7 minus 1 over 8
To find the result of 1 over 8 minus 3 over 7 minus 1 over 8, we can first simplify each of the fractions by finding a common denominator.
The common denominator for 8 and 7 is 56. So, we can rewrite 1 over 8 as 7 over 56 and 3 over 7 as 24 over 56.
Now, we can subtract the fractions: (7/56) - (24/56) - (1/8).
The numerators of the fractions can be subtracted directly since they have the same denominator:
7 - 24 - 1 = -18.
The denominator remains the same: 56.
Therefore, the result is -18/56 or simplified, -9/28.
