Answer 1

2\frac{1}{2}+3\frac{3}{4}-4\frac{2}{3}= 2\frac{6}{12}+3\frac{9}{12}-4\frac{8}{12}=

6\frac{3}{12} -4\frac{8}{12}= 1\frac{7}{12}

 

 

5\frac{4}{9}-3\frac{1}{2}+1\frac{2}{3}=

5\frac{8}{18}-3\frac{9}{18}+1\frac{12}{18}= 3\frac{11}{18}

 

(8:4\frac{4}{7})*1\frac{3}{7}= (8:\frac{32}{7})* \frac{10}{7}=

(8 * \frac{7}{32})* \frac{10}{7}=  \frac{56}{32} * \frac{10}{7}= \frac{40}{16} = 2,5

 

16:(3\frac{1}{3}*\frac{2}{5})= 16:(\frac{10}{3}*\frac{2}{5})=

16: \frac{4}{3}=  16 * \frac{3}{4}= 12
