Answer 1

$9\frac{4}{7} +7\frac{1}{9} =\frac{67*9+64*7}{63} =\frac{1051}{63} =16\frac{43}{63} \\18\frac{2}{15}+7\frac{1}{9} =\frac{272*3+64*5}{45}= \frac{1136}{45} =25\frac{11}{45} \\24\frac{3}{5}-7\frac{7}{8}=\frac{123*8-63*5}{40}=\frac{669}{40} =16\frac{29}{40} \\17\frac{7}{12}-8\frac{4}{8} =\frac{211*2-68*3}{24}= \frac{218}{24} =9\frac{2}{24} =9\frac{1}{12}$

$4\frac{3}{8}:7=\frac{35}{8}:\frac{7}{1}=\frac{35*1}{8*7} =\frac{5}{8} =0,625\\12\frac{2}{15} *3=\frac{182}{15}*\frac{3}{1} =\frac{182}{5} =36,4\\2\frac{3}{19}:41= \frac{41}{19}:\frac{41}{1}=\frac{41*1}{19*41}=\frac{1}{19}\\15\frac{2}{3}*14=\frac{47}{3}*\frac{14}{1}= \frac{658}{3} =219\frac{1}{3}$

$(14\frac{3}{8}-9\frac{1}{4})*24-(43\frac{4}{9}-19):3 =(\frac{115}{8} -\frac{74}{8})*24-( \frac{391}{9}- \frac{171}{9}):3= \frac{41*24}{8*1} -\frac{220*1}{9*3}= 123-\frac{220}{27} =\frac{3321-220}{27} =\frac{3101}{27} =114\frac{23}{27}$
