a. 2 5/8
b. 2
c. 17/32
d. 7/8

Explanation:

Step1: Convert mixed - number to improper fraction

$1\frac{3}{4}=\frac{4\times1 + 3}{4}=\frac{7}{4}$

Step2: Find a common denominator

The common denominator of 4 and 8 is 8. $\frac{7}{4}=\frac{7\times2}{4\times2}=\frac{14}{8}$

Step3: Add the fractions

$\frac{14}{8}+\frac{7}{8}=\frac{14 + 7}{8}=\frac{21}{8}=2\frac{5}{8}$

Answer:

$2\frac{5}{8}$
