Question

1¼+5⅔=
8,8/4-4,5/10=

Answer 1

5/4 + 17/3 = 83/12

2.2 - 0.45 = 1.75

Answer 2

1)
$1 \frac{1}{4} +5 \frac{2}{3} = \frac{5}{4} + \frac{17}{3} = \frac{3(5)+4(17)}{12} = \frac{83}{12}$

2)
$\frac{8,8}{4} - \frac{4,5}{10}= \frac{ \frac{44}{5} }{4} - \frac{ \frac{9}{2} }{10} = \frac{11}{5}- \frac{9}{20}= \frac{4(11)-9}{20}= \frac{35}{20}= \frac{7}{4}$
