Answer:

Yes.

Step-by-step explanation:

Example: 3¼ plus 2½

1. Make 3¼ an improper fraction. [tex]\frac{13}{4}[/tex]

2. Make the second number improper. [tex]\frac{5}{2}[/tex]

3. Find the common denominators. [tex]\frac{13}{4}[/tex]+[tex]\frac{10}{4}[/tex](for the second fraction, multiply both the numerator and denominator by 2).

4. Add the numerators. [tex]\frac{23}{4}[/tex] = 5[tex]\frac{3}{4}[/tex]
