Question

Вичислите:
А)1цел2/3+3цел3/4
Б)4цел3/5-1цел4/5
В)10цел5/32*13цел7/5
Г)12цел3/8:10цел5/16

Answer 1

$1 frac{2}{3}+3 frac{3}{4}= frac{5}{3}+ frac{15}{4}= frac{20+45}{12}= frac{65}{12} =5 frac{5}{12}$
$4 frac{3}{5} -1 frac{4}{5}= frac{23}{5} - frac{9}{5}= frac{23-9}{5}= frac{14}{5}= 2 frac{8}{10}=2,8$
$10 frac{5}{32}*13 frac{7}{5}= frac{325}{32} * frac{72}{5}= frac{65*36}{16}= frac{2340}{16}= 146,25$
