Question

What's 80 1/2 divided by 2/5

Answer 1

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

Answer 2

`80(1)/(2):(2)/(5)=(80\cdot2+1)/(2):(2)/(5)=(161)/(2)\cdot(5)/(2)=(805)/(4)=(804+1)/(4)=(804)/(4)+(1)/(4)=\boxed{201(1)/(4)}`
