Help me pleaseee

Answer 1

$1\frac{5}{7} +4\frac{3}{13} :1\frac{19}{26}= 1\frac{5}{7}+\frac{55*26}{13*45} =1\frac{5}{7}+\frac{11*2}{1*9} =1\frac{5}{7}+\frac{22}{9} =1\frac{5}{7}+2\frac{4}{9}=1\frac{45}{63} +2\frac{28}{63} =3\frac{73}{63} =4\frac{10}{63}$

$\frac{47}{48} :3\frac{13}{27} +\frac{13}{16}=\frac{47*27}{48*94} +\frac{13}{16}=\frac{1*9}{16*2} +\frac{13}{16}=\frac{9}{32} +\frac{13}{16}=\frac{9}{32}+\frac{26}{32} =\frac{35}{32}=1\frac{3}{32}$
