To simplify division, understanding basic fractions and decimal conversions is key. When dividing 12 by 9, the result is not a whole number, so it will be expressed as a fraction or decimal. Here’s how to do it simply:
Understanding the Division
First, let’s divide 12 by 9:
12 ÷ 9 =?
This can be done using long division, but for simplicity, let's convert it into a fraction and then into a decimal.
Fractional Representation
12 divided by 9 can be represented as a fraction:
12/9
To simplify this fraction, we look for a common divisor, which in this case is 3. So, we divide both the numerator and the denominator by 3:
(12 ÷ 3) / (9 ÷ 3) = 4/3
Decimal Representation
To convert the fraction 4/3 into a decimal, we divide the numerator by the denominator:
4 ÷ 3 = 1.333...
So, 12 divided by 9 equals 1.333..., which is a repeating decimal.
Practical Application
Understanding how to convert fractions to decimals is useful in various mathematical operations and real-world applications, such as cooking, construction, and science. For instance, if a recipe calls for 12 tablespoons of an ingredient and you want to divide it evenly among 9 servings, knowing the result of 12 divided by 9 helps in precise measurement.
Summary
Dividing 12 by 9 results in 1.333..., which can be represented as the fraction 4/3. This simple calculation demonstrates how fractions and decimals are interconnected and how converting between them can make mathematical operations more straightforward.
