How can you find the whole when you know part and the percent.

Usimov [2.4K]

An example should make this clear.

If $50 is 40% what is the value of the whole amount?

Answer:- Whole amount = 100^%

By proportion this = (100/ 40) * 50

= 2.5 * 50

= $125 (answer)

What are the solution(s) to the quadratic equation 9x2 = 4?

Oksanka [162]

we have

$9x^{2}=4$

Divide both sides by $9$

$9x^{2}/9=4/9$

$x^{2}=4/9$

Square root both sides

$x=(+/-)\sqrt{\frac{4}{9}}$

$x=(+/-)\frac{2}{3}$

the solutions are

$x1=\frac{2}{3}$

$x2=-\frac{2}{3}$

therefore

<u>the answer is the option</u>

x = 2/3 and x = -2/3

I added three non-unit fractions together to make a whole. What three fractions could that be?

Anna11 [10]

Answer:

For example $\frac{2}{6}$

Step-by-step explanation:

A non-unit fraction is a fraction of which the numerator is not equal to one. Additionally, the question does not state to pick three different ones and thus you can pick any fraction that when multiplied by three (since you take three fractions together) add up to a whole number (I'm picking the whole number to be one here just to make it simple), where the numerator is not equal to one of course.

For example: $\frac{2}{6}$ , because 3· $\frac{2}{6}$ = $\frac{6}{6}$ = 1

Infinitely many solutions can be found: for example $\frac{3}{9} , \frac{4}{12} , etc$
