1 1/2 divided by 1/2

$$\dfrac{
1\frac{1}{2} }
{\frac{1}{2} }\\\\
=\dfrac{
1+\frac{1}{2} }
{\frac{1}{2} }\\\\
=\dfrac{ 1 } {\frac{1}{2} }
+\dfrac{ \frac{1}{2} } {\frac{1}{2} }\\\\
=\dfrac{ 1 } {\frac{1}{2} }
+1\\\\
=1\cdot \frac{2}{1} }
+1\\
= 2+1\\
=3$$

 

or

$$\dfrac{
1\frac{1}{2} }
{\frac{1}{2} }\\\\
=
\dfrac{
\frac{3}{2} }
{\frac{1}{2}
}\\\\
=
\frac{3}{2} \cdot
\frac{2}{1} \\
=3$$

$$1 \frac{1}{2} = \frac{3}{2}$$

$$\frac{{(\frac{3}{2})}}{2} = \frac{3}{2 \cdot 2} = \frac{3}{4}$$

or

$$1\frac{1}{2} = 1.5$$

$$\frac{1.5}{2} = 0.75$$
