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]
$\frac{48}{10} - \frac{65}{30}= \frac{144-65}{30} = \frac{79}{30} = 2 \frac{19}{30}$
