Question

PLS ESTIMATE/ 67% of 8.7

Answer 1

67 percent of 8.7

$\frac{67}{100} \times \frac{x}{8.7}$
$100x = 67 \times 8.7$

$100x = 582.9$

Divide by 100 on both sides to isolate the x

$x = 5.829$
Round up (to the nearest tenth place and whole number)

$x = 6$
$x = 5.8$

Answer 2

Estimate to me means put away your calculator. Just for stopping you from doing that the exact answer is 5.829

That's not an estimate. An estimate is the approximate answer. 67 % is roughly 67/100 which is very nearly 2/3

2/3 = 0.66666667 so 67/100 = 0.67 is close enough to 2/3

8.7 is close to 9.

So an estimated answer is 2/3 * 9 = 18/3 = 6 and that is close enough.

Every math class you take, you should take an ability to estimate the answers from the class. That is a very important skill. When you are doing a test, you should know if your answers make sense by estimation,
