Answer: 0.3 as a fraction is 3/10
Writing a decimal as a fraction is a fundamental skill in mathematics that helps convert numbers between two different formats. Decimals like 0.3 can be represented exactly as fractions, making it easier to perform certain mathematical operations or to compare values. Let’s explore how to turn 0.3 into a fraction with clear steps.
Methods
Math Tutor Explanation Using the Place Value Method
This method uses the place value of the decimal to write it as a fraction, then simplifies if possible.
Step 1: Step 1: Recognize that the digit 3 is in the tenths place, so 0.3 = 3/10
Step 2: Step 2: Check if the fraction 3/10 can be simplified (it cannot, so this is the simplest form)
Math Tutor Explanation Using the Equation Method
Another approach is to set the decimal equal to a variable and solve for the fraction by eliminating the decimal.
Step 1: Step 1: Let x = 0.3
Step 2: Step 2: Multiply both sides by 10 to get rid of the decimal, so 10x = 3
Step 1:
Step 2:
