Explanation
The given question is asking to convert the given mixed numbers into improper fractions. To convert a mixed number to an improper fraction, we multiply the whole number by the denominator of the fraction and add the numerator. Then we write the sum as the numerator and keep the denominator the same. In this case, 1 multiplied by 3 is 3 and adding the numerator 1 gives us 4. Therefore, the improper fraction is 4/3. However, since the question specifically asks for a subtraction, we subtract the second fraction from the first. 4/3 minus 7/2 is equal to 7/2.
