To compare the fractions \( \frac{1}{2} \), \( \frac{5}{8} \), and \( \frac{9}{16} \), we can convert them to a common denominator or convert them to decimals.
- Convert to decimals:
- \( \frac{1}{2} = 0.5 \)
- \( \frac{5}{8} = 0.625 \)
- \( \frac{9}{16} = 0.5625 \)
Now, we can order them based on their decimal values:
- \( 0.5 < 0.5625 < 0.625 \)
So the order from least to greatest is:
- \( \frac{1}{2} \)
- \( \frac{9}{16} \)
- \( \frac{5}{8} \)
This corresponds to option B: 1/2 , 9/16 , 5/8.
