Answer :

LetsBeMe
80.5 ÷ 0.4 = 201.25
Or 
80 ½ ÷ 2/5 = 201 ¼
You can convert it to decimal form and do long division which I find slightly faster or multiply by the reciprocal. Your choice
[tex]80\frac{1}{2}:\frac{2}{5}=\frac{80\cdot2+1}{2}:\frac{2}{5}=\frac{161}{2}\cdot\frac{5}{2}=\frac{805}{4}=\frac{804+1}{4}=\frac{804}{4}+\frac{1}{4}=\boxed{201\frac{1}{4}}[/tex]
