Solution steps

3 + 3 \frac{3}{4}

Convert mixed numbers to improper fractions:

3 \frac{3}{4} = \frac{15}{4}

= 3 + \frac{15}{4}

Convert element to fraction:

3 = \frac{3 \cdot 4}{4}

= \frac{3 \cdot 4}{4} + \frac{15}{4}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{3 \cdot 4 + 15}{4}

3 \cdot 4 + 15 = 27

= \frac{27}{4}

Convert improper fractions to mixed numbers:

\frac{27}{4} = 6 \frac{3}{4}

= 6 \frac{3}{4}
