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.
