Answer 1

$\frac{3}{4} + \frac{1}{3} = \frac{(12:4.3)+(12:3.1)}{12} = \frac{9+4}{12} = \frac{13}{12}$

$\frac{1}{5} + \frac{3}{8} = \frac{(40:5.1)+(40:8.3)}{40} = \frac{8+15}{40} = \frac{23}{40}$

$\frac{5}{3} - \frac{8}{9} + \frac{7}{3} = \frac{(9:3.5) - (9:9.8) + (9:3.7)}{9} = \frac{15-8+21}{9} = \frac{28}{9}$

$\frac{4}{5} + \frac{11}{13} - \frac{7}{10} = \frac{(130:5.4)+(130:13.11)-(130:10.7)}{130} = \frac{104+110-91}{130} = \frac{123}{130}$

$\frac{3}{11} - \frac{2}{13} = \frac{(143:11.3)-(143:13.2)}{143} = \frac{39-22}{143} = \frac{17}{143}$

$\frac{7}{6} + \frac{3}{2} - \frac{2}{11} = \frac{(66:6.7)+(66:2.3)-(66:11.2)}{66} = \frac{77+99-12}{66} = \frac{164}{66} = \frac{82}{33}$

$\frac{7}{2} - \frac{5}{4} - \frac{4}{5} = \frac{(20:2.7)-(20:4.5)-(20:5.4)}{20} = \frac{70-25-16}{20} = \frac{29}{20}$

$\frac{15}{4} + \frac{12}{9} + \frac{4}{15} = \frac{(360:4.15)+(360:9.12)+(360:15.4)}{360} = \frac{1350+480+96}{360} = \frac{1926}{360} = \frac{214}{40}$ = $\frac{107}{20}$
