$\frac{11}{4}$ $11/4$

Step 1) Convert the mixed fractions into improper fractions:

$((\frac{4}{4}) \cdot 1 + \frac{1}{4}) + ((\frac{2}{2}) \cdot 1 + \frac{1}{2})$ $((4/4)*1 + 1/4) + ((2/2)*1 + 1/2)$

$(\frac{4}{4} + \frac{1}{4}) + (\frac{2}{2} + \frac{1}{2})$ $(4/4 + 1/4) + (2/2 + 1/2)$

$\frac{5}{4} + \frac{3}{2}$ $5/4 + 3/2$

Step 2) Get both fractions over a common denominator (in this case $4$ $4$ ) by multiplying the second fraction by the necessary form of $1$ $1$ :

$\frac{5}{4} + ((\frac{2}{2}) (\frac{3}{2}))$ $5/4 + ((2/2)(3/2))$

$\frac{5}{4} + \frac{6}{4}$ $5/4 + 6/4$

$\frac{11}{4}$ $11/4$
