What is the value of 7/8 minus 1/8? (different phrasing)

• A. 1/2
• B. 7/8
• C. 2/8
• D. 3/4

Answer: (D)

Subtracting fractions with the same denominator keeps the denominator and subtracts the numerators. Here you’re counting the same number of equal parts of a whole: take seven of the eight parts and remove one part, leaving six parts out of eight. That’s 6/8, which simplifies by dividing numerator and denominator by 2 to 3/4. So the value is three quarters.
