Question

(21)(-4)(3)(1 over 5)(5) 1 over 5 is a fraction

Answer 1

I hope this is the expression you want to write:
$(21)(-4)(3)(\frac{1}{5})(5) (\frac{1}{5})$
At first we can convert all the integers in fraction form. So,

$(\frac{21}{1})(-\frac{4}{1})(\frac{3}{1})(\frac{1}{5})(\frac{5}{1}) (\frac{1}{5})$
Next step is to multiply the numerators and denominators. So,
$\frac{21*(-4)*3*1*5*1}{1*1*1*5*1*5}$
=-$\frac{1260}{25}$
=-$\frac{252}{5}$
