b) 19/5 + 21/10= 190+105/50=295/50= 5 45/50

Answer 2

$3 \frac{4}{5} + 2 \frac{1}{10} = \frac{19}{5} + \frac{21}{10} = \frac{38 + 21}{10} = \frac{59}{10} = 5 \frac{9}{10}$

$\frac{12}{4} + 1 \frac{3}{8} = \frac{12}{4} + \frac{11}{8 } = \frac{24 + 11}{8} = \frac{35}{8} = 4 \frac{3}{8}$

$5 \frac{11}{ 12} + 2 \frac{1}{6} = \frac{71}{12 } + \frac{13}{6} = \frac{71 + 26}{12} = \frac{97}{12} = 8 \frac{1}{12}$

$10 \frac{5}{6} - 9 \frac{1}{8} = \frac{65}{6} - \frac{73}{8} = \frac{260 - 219}{24} = \frac{41}{24} = 1 \frac{17}{24}$

$8 \frac{4}{5} - 6 \frac{4}{3} = \frac{44}{5} - \frac{22}{3} = \frac{132 - 110}{15} = \frac{22}{15} = 1 \frac{7}{15}$

$2 \frac{1}{2} + \frac{12}{2} + 1 \frac{1}{4} = \frac{5}{2} + \frac{12}{2} + \frac{5}{4} = \frac{10 + 24 + 5}{4} = \frac{39}{4} = 9 \frac{3}{4}$

$1 \frac{7}{8} + \frac{8}{4} + 3 \frac{5}{16} = \frac{15}{8} + \frac{8}{4} + \frac{53}{16} = \frac{30 + 32 + 53}{16} = \frac{115}{16} = 7 \frac{3}{16}$

$\frac{20}{3} - 1 \frac{1}{2} - 4 \frac{1}{12} = \frac{20}{3} - \frac{3}{2} - \frac{49}{12} = \frac{80 - 18 - 49}{12} = \frac{13}{12} = 1 \frac{1}{12}$
