Question

(3‚8:9‚5+3‚9:1‚5-1 целая 5/8) : 0‚75

Answer 1

(3‚8:9‚5+3‚9:1‚5-1 целая 5/8) : 0‚75 = $( frac{38}{10} * frac{10}{95} + frac{39}{10} * frac{10}{15} - frac{13}{8} ) / 0,75 = [tex]frac{38}{95}* frac{100}{75} + frac{39}{15}*frac{100}{75} - frac{13}{8}*frac{100}{75} = frac{1900}{1425} + frac{780}{225} - frac{325}{150} = frac{5700+14820}{4275}- frac{325}{150} =$ = [/tex]
$frac{48}{10} - frac{65}{30}= frac{144-65}{30} = frac{79}{30} = 2 frac{19}{30}$
