What decimal is 7/8?

• A. 0.885
• B. 0.825
• C. 0.95
• D. 0.875

Answer: (D)

Dividing the numerator by the denominator turns a fraction into a decimal. For 7 divided by 8, you see how many times 8 fits into 7. It doesn’t fit, so you write 0. and bring down a zero to continue. 8 goes into 70 eight times (8 × 8 = 64), leaving a remainder of 6. Bring down the next zero to make 60; 8 goes into 60 seven times (7 × 8 = 56), leaving a remainder of 4. Bring down another zero to make 40; 8 goes into 40 five times (5 × 8 = 40), with no remainder. So the decimal is 0.875. This is an exact decimal representation, not a repeating pattern.

The other decimals are not equal to 0.875, so they don’t match 7/8.
