To determine

To calculate: the expression $k\%\text{ of 67}$ when $\text{k=10}$ .

Answer to Problem 51E

The value of expression $k\%\text{ of 67}$ is $\text{6}\text{.7}$ when $\text{k=10}$

Explanation of Solution

Given information: consider, the expression provided in the question,

  $k\%\text{ of 67}$ .

Calculation:to solve the expression first substitute k by 10 then, write percent as a decimal then multiply.

  $\begin{array}{l}k\%\text{ of 67 }\\ 10\%\text{ of 67}\\ \text{.10}·\text{67}\\ \text{6}\text{.7 }\end{array}$

Hence,

Thus,The value of expression $k\%\text{ of 67}$ is $\text{6}\text{.7}$ when $\text{k=10}$ .
