Sooooooooo who here is good at mathhhh not meh

Answer:
The answer as a mixed number is [tex]=15\frac{3}{4}.[/tex]
Step-by-step explanation:
Given:
5 1/4 ÷ 1/3.
Now, to solve as a mixed number in simplest form.
[tex]5\frac{1}{4} \div \frac{1}{3}[/tex]
Now, changing the mixed fraction into improper:
[tex]=\frac{21}{4} \div \frac{1}{3}[/tex]
So, to solve we change the division into multiplication.
Thus, R.H.S of the fraction will get reverse:
[tex]=\frac{21}{4} \times \frac{3}{1}[/tex]
[tex]=\frac{63}{4}[/tex]
Now, changing the improper fraction into mixed:
[tex]=15\frac{3}{4} .[/tex]
Therefore, the answer as a mixed number is [tex]=15\frac{3}{4} .[/tex]
