In a recent poll 60% of the middle school preferred pizza for lunch on Friday 27% prefer tacos and 13% preferred hotdogs the mid

serious [3.7K]

Answer:

516 students preferred pizza

Step-by-step explanation:

To solve this problem we have to calculate 60% of the total students (860)

To get the percentage of a number we have to divide by 100 and then multiply by the number it indicates, in this case 60

860 %60 = 860 / 100 * 60

860 / 100 * 60 =

8.6 * 60 = 516

60% of 860 is 516

this means that for Friday lunches 516 students preferred pizza

What is the value of the expression (-8/9) divided by (-2/3) x (-4 1/2) ?

Law Incorporation [45]

Answer:

B) $x=-\frac{8}{27}$

Step-by-step explanation:

$-\frac{8}{9}=-\frac{2}{3}x(-4\frac{1}{2})$

To start things off, lets convert any <em>mixed numbers</em> like $-4\frac{1}{2}$ into <em>improper fractions</em>. In this case $-4\frac{1}{2}$ as an improper fraction is $-\frac{9}{2}$ .

$-\frac{8}{9}=-\frac{2}{3}x(-\frac{9}{2})$

Now let's multiply $-\frac{2}{3}x$ by $-\frac{9}{2}$ . When multiplying fractions, all you need to do is multiply the numerators and denominators separately. Your final answer should be $\frac{18}{6}x$ .
*Note: a <em>negative </em>times a <em>negative </em>is a <em>positive</em>, so that's why we now have an even number in front of $x$ instead of a negative number.

$-\frac{8}{9}=\frac{18}{6}x$

Now we want to isolate $x$ , so we'll have to divide $-\frac{8}{9}$ by $\frac{18}{6}$ , but dividing these two fractions seems like a pain. To make things a bit easier, let's turn our improper fraction into a whole number. To change this improper fraction into a whole number, we should ask ourselves what times $6$ is equal to $18$ ? In this case, the answer is 3, so $\frac{18}{6}$ is actually the same thing as the whole number $3$ .
*Note: In general, keeping fractions as either improper fractions or whole numbers will make doing math easier. Avoid mixed numbers like $-4\frac{1}{2}$ when trying to do math and simply change improper fractions into mixed numbers once you have your final solution.

$-\frac{8}{9}=3x$

Now divide $-\frac{8}{9}$ by $3$ . Think of it as multiplying the denominator of $-\frac{8}{9}$ by $3$ .

$-\frac{8}{27}=x$
