[tex] 1\frac{3}{4} [/tex] + [tex] \frac{11}{4} [/tex] + [tex] \frac{1}{16} [/tex]
1st step: Change the mixed fractions to improper fractions:
              [tex] 1\frac{3}{4} [/tex] = [tex] \frac{7}{4} [/tex]
2nd step: Find a common denominator 
               16 is the common denominator
 [tex] \frac{7*4}{4*4} [/tex] + [tex] \frac{11*4}{4*4} [/tex] + [tex] \frac{1}{16} [/tex]
=[tex] \frac{28+44+1}{16} [/tex]
=[tex] \frac{73}{16} [/tex]
As a mixed fraction:
=[tex] 4\frac{9}{16} [/tex]
13/4 rounds to about 3, 11/4 rounds to 3, and 1/16 rounds to 0. So a resonable estimate would be about 6.
