Explanation:
To find the difference between the two wingspans, we need to subtract the smaller one from the larger one. We can do this by using a common denominator of 4 and rewriting the fractions as equivalent fractions:
3⁄4 - 1⁄2 = 3⁄4 - 2⁄4 = (3 - 2)⁄4 = 1⁄4
So, the wingspan of the second owl is 1⁄4 foot longer than the wingspan of the first owl.
You can also write this answer as a decimal: 0.25 foot.
