to change a improper fraction you divide 22 by 5
so, 22 ÷ 5 = 4 r2
Since you have a whole number to be 4 you keep 4 as the whole number. You keep 2 as the numerator and 5 as the denominator so you get,
[tex] 4\frac{2}{5} [/tex]
to get back to [tex] \frac{22}{5} [/tex] you multiply 4 by 5 and then add two. So,
[tex](4*5)+2 = 22[/tex]. You will always have to keep the denominator the same when converting from one form to an another ===> [tex] \frac{22}{5} [/tex]
