Question

cu se efectueaza [1,3÷1,(4)+0,15]÷1,75=​

Answer 1

Răspuns:

Explicație pas cu pas:

1,3= $\frac{13}{10}$

1,(4)=$1\frac{4}{9} =\frac{13}{9}$

0,15=$\frac{15}{100} =\frac{3}{20}$

1,75=$\frac{175}{100} =\frac{7}{4}$

$[\frac{13}{10} * \frac{9}{13} +\frac{3}{20} ] : \frac{7}{4} =$

$[\frac{9}{10} +\frac{3}{20} ]:\frac{7}{4}=\\\frac{18}{20}+\frac{3}{20}]:\frac{7}{4}$=

$\frac{21}{20}*\frac{4}{7}=\frac{3}{5}$
