Convert to Fraction: To convert a decimal to a fraction, we need to consider the place value of the last digit in the decimal. In 0.21, the last digit, 1, is in the hundredths place, which means 0.21 can be written as 21 over 100.Calculation: 0.21=10021
Simplify Fraction: Now, we should simplify the fraction by finding the greatest common divisor (GCD) of the numerator and the denominator and then divide both by that number. The GCD of 21 and 100 is 1, so the fraction is already in its simplest form.Calculation: GCD(21,100)=1
Final Answer: Since the fraction cannot be simplified further, we have our final answer.Final Answer: 0.21 as a fraction is 10021.
