-23 + 13x
working:
(-2 x 2 + 9x - 3) - (7 x 2 - 4x + 2)
= (-4 + 9x -3) - (14 - 4x + 2)
= -7 + 9x - 16 + 4x
= -23 + 13x
-13 - 13x
9 - 13x
5x - 5

Find the mixed number equivalent to the im<br> proper fraction 22/6

Naddik [55]

Answer:

$3\frac{2}{3}$

Step-by-step explanation:

Given the following question:

$\frac{22}{6}$

In order to convert a mixed number into an improper fraction we have to divide the numerator (in this case; 22) by the denominator (in this case; 6) to find your answer.

$\frac{22}{6}$
$\frac{22}{6} \div2=\frac{11}{3}$
$\frac{11}{3}=11\div3=3\frac{2}{3}$
$=3\frac{2}{3}$

Let three represent how many times 3 goes into 11, let 2 represent the remainder while of course keeping the denominator the same. Your answer is "3 2/3."

Hope this helps.
