$11/4$

Step 1) Convert the mixed fractions into improper fractions:

$((4/4)*1 + 1/4) + ((2/2)*1 + 1/2)$

$(4/4 + 1/4) + (2/2 + 1/2)$

$5/4 + 3/2$

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

$5/4 + ((2/2)(3/2))$

$5/4 + 6/4$

$11/4$
