.875 AS A FRACTION: Everything You Need to Know
.875 as a fraction is a common mathematical expression that represents a decimal number as a fraction. In this comprehensive guide, we will walk you through the process of converting.875 to a fraction, provide practical tips, and offer additional information to help you understand this concept better.
Understanding the Basics
.875 is a decimal number that can be expressed as a fraction. To convert a decimal to a fraction, we need to understand the concept of place value and the relationship between decimals and fractions.
Place value is the value of a digit in a number based on its position. In the decimal.875, the 8 is in the tenths place, the 7 is in the hundredths place, and the 5 is in the thousandths place.
When converting a decimal to a fraction, we can use the following general rule: if the decimal has n digits after the decimal point, we can multiply it by 10^n to get an integer. Then, we can express the integer as a fraction.

Converting.875 to a Fraction
To convert.875 to a fraction, we can follow these steps:
- Write the decimal as a fraction with a denominator of 10^n, where n is the number of digits after the decimal point.
- Reduce the fraction to its simplest form by dividing both the numerator and denominator by their greatest common divisor (GCD).
Applying these steps to.875, we get:
.875 = 875/1000
To simplify the fraction, we need to find the GCD of 875 and 1000.
The GCD of 875 and 1000 is 125.
Now, we can divide both the numerator and denominator by 125 to get:
875 ÷ 125 = 7
1000 ÷ 125 = 8
So, the simplified fraction is 7/8.
