Chapter 7.4, Problem 45HP

To determine

To list:the two values of a.

Answer to Problem 45HP

  $66\frac{2}{3}\%$ of 6700 and 13400 is about 4489 and 8978 respectively.

Explanation of Solution

Given:

  $66\frac{2}{3}\%$ of a .

Calculation:

Assume two values of a as 6700 and 13400.

The expression is 67% of 6700 and 67% of 13400.

  $\begin{array}{c}67\%\text{of}6700=\frac{67}{100}\text{of}6700\text{Think}:67\%=\frac{67}{100}\\ =4489\text{Think}:\frac{67}{100}\text{of}6700\text{is}\text{about}4489.\end{array}$

And,

  $\begin{array}{c}67\%\text{of}6700=\frac{67}{100}\text{of}13400\text{Think}:67\%=\frac{67}{100}\\ =8978\text{Think}:\frac{67}{100}\text{of}13400\text{is}\text{about}8978.\end{array}$

Hence, $66\frac{2}{3}\%$ of 6700 and 13400 is about 4489 and 8978 respectively.

Conclusion:

Hence, $66\frac{2}{3}\%$ of 6700 and 13400 is about 4489 and 8978 respectively.
