Question

(0.2-7/15)x(-5/8)-(-5/12-0.75):2 1/3

Answer 1

$1)0,2- frac{7}{15} = frac{1}{5} - frac{7}{15} = frac{3-7}{15} =- frac{4}{15} \ 2)- frac{4}{15} *(- frac{5}{8} )= frac{1}{6} \ 3)- frac{5}{12} -0,75=- frac{5}{12} - frac{3}{4} =-( frac{5+9}{12} )=- frac{14}{12}=- frac{7}{6} \ 4) - frac{7}{6} :2 frac{1}{3} =- frac{7}{6} : frac{7}{3} =- frac{7}{6} * frac{3}{7} =- frac{1}{2} \ 5) frac{1}{6} -(- frac{1}{2} )= frac{1}{6}+ frac{1}{2} = frac{1+3}{6}= frac{4}{6} = frac{2}{3}$
