To compare two values using rational approximations, we typically pick two numbers or expressions and estimate their values using fractions or simpler terms.
For example, suppose we want to compare \( \frac{1}{3} \) and \( 0.25 \).
-
Convert the decimal to a fraction:
- \( 0.25 = \frac{25}{100} = \frac{1}{4} \).
-
Find a common denominator to compare:
- The least common multiple of 3 and 4 is 12.
- Convert \( \frac{1}{3} \) to a fraction with denominator 12: \[ \frac{1}{3} = \frac{4}{12}. \]
- Convert \( \frac{1}{4} \) to a fraction with denominator 12: \[ \frac{1}{4} = \frac{3}{12}. \]
-
Compare the fractions:
- Now we have \( \frac{4}{12} \) and \( \frac{3}{12} \).
- Since \( 4 > 3 \), we conclude that \( \frac{1}{3} > \frac{1}{4} \).
Thus, the inequality statement is:
\[ \frac{1}{3} > 0.25 \]
To apply this to another example, if you have two other rational approximations or expressions, you can follow a similar process to arrive at a comparative inequality. Please provide specific numbers or expressions if you want help comparing particular values!
