1 and 1/8 as a Decimal: Unraveling the Mysteries of Fractions

Fractions, those stubborn numbers that seem to give us endless trouble, can be tricky to understand. However, with the right approach, we can conquer the realm of fractions and unravel their secrets, transforming them into decimals we can easily comprehend. One such fraction that deserves our attention is one and one-eighth.

Converting 1 and 1/8 to a Decimal: A Step-by-Step Guide

To convert 1 and 1/8 to a decimal, we embark on a simple but effective three-step process:

Step 1: Convert the Mixed Number to an Improper Fraction

An improper fraction is a fraction with a numerator that is greater than or equal to its denominator. To convert 1 and 1/8 to an improper fraction, we multiply the whole number (1) by the denominator (8) and add the numerator (1), giving us:

1 and 1/8 = (1 * 8) + 1 = 9

Therefore, the improper fraction equivalent of 1 and 1/8 is 9/8.

Step 2: Divide the Numerator by the Denominator

Now, we simply divide the numerator by the denominator to obtain the decimal equivalent. In this case, we have:

9 ÷ 8 = 1.125

Step 3: Round off the Decimal (Optional)

Depending on the level of accuracy required, we can round off the decimal to the desired number of decimal places. For most applications, rounding to three decimal places is sufficient, giving us:

1 and 1/8 ≈ 1.125
