To evaluate two fractions being divided, you must turn the right fraction into a reciprocal. That means you must put the bottom number at the top and then put the top number on the bottom (you’re basically switching them).

8/13 / 3/2

Now, once you turned the other number into a reciprocal, you multiply across. The top number times the other top number and do this to the bottom numbers, too.

8/13 * 3/2 = 24/26

You found the answer, 24/26. But as you can see, it’s not one of the choices. That’s because you need to simplify.

24/26 / 2/2 = 12/13

12/13 is your answer, or choice C!

I hope this helped. Comment below if you have any questions.

2. Jessica's financial advisor believes that she should spend no more than 28% of her gross monthly income for housing. She has

scoray [572]

Jessica's annual salary is $68571.43.

Data;

percentage saved for housing = 28%
amount saved annually = $1600

<h3>Percentage</h3>

This is the ratio of a number to the entire value and multiplied by 100

The percentage set aside for housing is given as 28% which is $1600.

Let find 28% of x which is equal to 1600

$\frac{28}{100} = \frac{1600}{x}$

cross multiply both sides and solve for x

$\frac{28}{100} = \frac{1600}{x}\\ 28*x = 100*1600\\28x = 160000\\$

Divide both sides by the coefficient of x

$\frac{28x}{28} = \frac{160000}{28}\\ x = 5714.28$

Her monthly income is $5714.28.

Let's multiply this by 12 (months in a year) to determine her gross monthly income.

$5714.28*12 = 68571.43$

From the above calculations, Jessica's annual salary is $68571.43.

All of the following are epuivalent forms 9/11 except

meriva

Answer: Except (4) but see detail below

Precisely speaking, $\frac{9}{11}=0.\overline{81}=0.818181....$

Looking over the choices, only 72/88 = 9/11 is precisely "equivalent" so all of (1), (2), and (4) would be EXCEPT.

But because K12 teachers' language may sometimes be sloppy, "equivalent" may also mean "approximate." If that is the case (I let you make the call if the premise is true): the following are definitely not 9/11:

1.22 (is greater than 1)

It could also be that the original question had the "overline" mark to mean "periodic" over the 81 parts, like this:

$0.\overline{81}\\0.\overline{8181}$
