$\frac{ 3 }{ 2 } \times \frac{ 2 }{ 3 }s=\frac{ 3 }{ 2 } \times \left( -8 \right)$
Cancel out the greatest common factor $3$$\frac{ 1 }{ 2 } \times 2s=\frac{ 3 }{ 2 } \times \left( -8 \right)$
Cancel out the greatest common factor $2$$s=\frac{ 3 }{ 2 } \times \left( -8 \right)$
Multiplying a positive and a negative equals a negative: $\left( + \right) \times \left( - \right)=\left( - \right)$$s=-\frac{ 3 }{ 2 } \times 8$
Cancel out the greatest common factor $2$$s=-3 \times 4$
Multiply the numbers$s=-12$
