Question

Calvin evaluated -2/3 *5 1/6 using the steps below.

Answer 1

For this case we have to evaluate the following expression,

$- \frac {2} {3} * 5 \frac {1} {6}$

We must follow the steps below:

We convert the mixed number into a fraction:

$- \frac {2} {3} * \frac {6 * 5 + 1} {6} =\\- \frac {2} {3} * \frac {31} {6} =$

We multiply the fractions, taking into account that:

$- * + = -\\- \frac {2 * 31} {3 * 6} =\\- \frac {62} {18} =$

We simplify:

$- \frac {31} {9}$

We convert to mixed number:

$-3 \frac {4} {9}$

Answer:

$-3 \frac {4} {9}$
