#11/4#

Explanation:

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#
