we know that
A rate is a ratio that compares quantities in different units. and a unit rate is a rate where the second quantity is one unit.
in this problem
[tex] Rate=\frac{46}{5} \frac{usd}{toys} [/tex]
to convert rate to unit rate divide by [tex] 5 [/tex] numerator and denominator
[tex] unit.rate=\frac{\frac{46}{5}}{\frac{5}{5}} \\ \\ unit.rate=\frac{9.2}{1} \frac{usd}{toys} [/tex]
therefore
the answer is
The unit rate is equal to [tex] \frac{9.2}{1} \frac{usd}{toys} [/tex]
