Answer:

Step-by-step explanation:

When you add 1\4 and 3\4, that equals 1 foot. 3+4 equals 7. 7+1 equals 8 feet and if you convert 8 feet into inches, that equals 96. {I did this in my head so it may be wrong lol}

let's firstly convert the mixed fractions to improper fractions, and then use the LCD, which in this case is 4, to sum them up.

$\bf \stackrel{mixed}{3\frac{1}{4}}\implies \cfrac{3\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{13}{4}}~\hfill \stackrel{mixed}{4\frac{3}{4}}\implies \cfrac{4\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{19}{4}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{13}{4}+\cfrac{19}{4}\implies \stackrel{\textit{using the LCD of 4}}{\cfrac{13+19}{4}}\implies \cfrac{32}{4}\implies 8$

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

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.
