Understanding Fractions in Decimal Form
To convert the fraction 7 over 8 into a decimal, we need to divide the numerator (7) by the denominator (8). This process involves simple division. The fraction 7⁄8 is equivalent to 7 ÷ 8.
Performing the Division
When we divide 7 by 8, we are essentially finding out how many times 8 fits into 7. Given that 8 is larger than 7, the result will be less than 1. Performing the division: 7 ÷ 8 = 0.875.
| Fraction | Decimal Equivalent |
|---|---|
| 7/8 | 0.875 |
