Problem
Use the properties of real numbers to simplify the expression. \[ \frac{6}{7}(-0.42)\left(\frac{7}{6}\right) \] \[ \frac{6}{7}(-0.42)\left(\frac{7}{6}\right)= \] (Simplify your answer. Type an integer or a decimal.)
Solution
Step 1 ：Use the properties of real numbers to simplify the expression. \[\frac{6}{7}(-0.42)\left(\frac{7}{6}\right)\]
Step 2 ：The fraction \(\frac{6}{7}\) and \(\frac{7}{6}\) will cancel each other out, leaving only \(-0.42\) to be multiplied by 1.
Step 3 ：The simplified expression is \(\boxed{-0.42}\).
