Find the least common denominator (LCD), then rewriting each term as an equivalent fraction with the LCD.
Then we compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least.
LCD of \(2, \ 8, \ 4\) and \(16\) is \(16\).
Rewrite the input fractions as equivalent fractions using the LCD:
