Put these in order, smallest first:

0.5

75%

2/3

0.5 = 0.5

75% = 0.75

2/3 = 0.6666666 ...

In order, from smallest to greatest, it would be 0.5, ²/₃, 75%.

Your final answer is 0.5, ²/₃, 75%.

smallest to greatest: 0.50, 2/3, 75%

We need to get each number into a common form to easily compare one another. We can use the decimal form.

0.50 = 0.50 * smallest

75% = 0.75 * largest

2/3 = 0.67 * middle

Or we can convert each number to percentage form:

0.50 * 100% = 50%

75% = 75%

2/3 * 100% = 67%

We can also convert each number into fractions. Just solve for the common denominator.
