1. 7 3/4 – 2 3/2 =2. 1/2 – 14/6 + 3/1 = 3. 4 2/5 + 5 3/4 – 2 1/2 =

$1. : 7 frac{3}{4} - 2 frac{3}{2} = frac{31 times 1}{4} - frac{7 times 2}{2} = frac{31}{4} - frac{14}{4} = frac{17}{4} = 4 frac{1}{4}$

$2. : frac{1 times 3}{2} - frac{14 times 1}{6} + frac{3 times 6}{1} = frac{3}{6} - frac{14}{6} + frac{18}{6} = frac{32}{6} - frac{3}{6} = frac{29}{6} = 4 frac{5}{6}$

$3. : 4 frac{2}{5} + 5 frac{3}{4} - 2 frac{1}{2} = frac{22 times 4}{5} + frac{23 times 5 times 10}{4} - frac{5}{2} = frac{88}{20} + frac{155}{20} - frac{50}{20} = frac{243}{20} - frac{50}{20} = frac{193}{20} = 9 frac{13}{20}$
