Answer:

Yes, they are equivalent.

Step-by-step explanation:

Both of the expressions equal to 77. 42+35 is easy, just add to get 77. To solve 7(6+5) remember PEMDAS which tells you to do parentheses first. So add 6+5, which is 11, then multiply by 7. 11*7 is 77, therefore the expressions are equivalent.

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.
