решение следующей пропорции 6 3/7 :1 6/7 = 4,5 : x

Ответ

Автор - BJIADA
6 frac{3}{7} : 1 frac{6}{7} = 4,5 : x<br />
\ 6  frac{3}{7}x=4.5 * 1  frac{6}{7}<br />
\ frac{45}{7}x= frac{117}{14}<br />
\ x=      frac{117}{14} : frac{45}{7}<br />
\x= frac{117}{90}<br />
\x=1 frac{27}{90}<br />
\x=1 frac{3}{10}<br />
\x=1.3
