The correct answer is C.
Let x be the number. Then:
\(\frac{1}{6 } x = 6 \frac{1}{3 }x – 2 \frac{7}{15} ⇒ 6 \frac{1}{3 }x – \frac{1}{6 } x = 2 \frac{7}{15 } ⇒ \frac{37}{6 }x = \frac{37}{15 }\)
\(X = \frac{2}{5 }\)
Then:
\(1 \frac{4}{5 } x = \frac{9}{5 } × \frac{2}{5 } = \frac{18}{25 }\)
\(4 – (\frac{18}{25 }) = \frac{37}{25 } =\frac{82}{25 }\)The Absolute Best Books to Ace Algebra
