Question

(2\(\frac{4}{5}\).x.50):\(\frac{2}{3}\)=-51, ? x

Answer 1

\(\left(2\frac{4}{5}\times x\times50\right)\div\frac{2}{3}=-51\)

\(\left(\frac{14}{5}\times x\times50\right)=-51.\frac{2}{3}\)

\(\left(\frac{14}{5}\times x\times50\right)=-34\)

\(\frac{14}{5}x=-34:50\)

\(\frac{14}{5}x=-\frac{17}{25}\)

\(x=-\frac{17}{25}:\frac{14}{5}\)

\(x=-\frac{17}{70}\)
