Question

ВЫЧИСЛИТЬ ( 2.48 + 3 ЦЕЛЫХ 5/9 * 1 ЦЕЛЫХ 1 / 8 ) /( 6.1 - 3.7 )

Answer 1

$(2.48+3 frac{5}{9}*1 frac{1}{8} ):(6.1-3.7)=(2 frac{48}{100}+ frac{32}{9}* frac{9}{8} ):2 frac{4}{10}=( frac{62}{25}+ frac{32}{4} )* frac{5}{12}=$$( frac{62}{25}+ frac{32}{4} )* frac{5}{12}= frac{62*4+32*5}{100}* frac{5}{12}= frac{408}{100}* frac{5}{12}= frac{17*2*12*5}{5*10*2*12}= frac{17}{10}=1 frac{7}{10}=1,7$
