we know that
The Inverse Property of Multiplication states that the product of any number and its multiplicative inverse is one
so
[tex]\frac{a}{b}* \frac{b}{a}=1[/tex]
in this problem we have
[tex]\frac{a}{b}=\frac{17}{3}[/tex]
[tex]\frac{b}{a}=\frac{3}{17}[/tex] -----> multiplicative inverse of [tex]\frac{a}{b}[/tex]
substitute
[tex]\frac{17}{3}*\frac{3}{17}=1[/tex]
therefore
the answer is
inverse property of multiplication
