Answer:
1) [tex] 8.7\ \frac{meters}{hour}[/tex]
2) [tex]1.92\ \frac{points}{game}[/tex]
3) [tex]1.25\ \frac{strikeouts}{inning}[/tex]
4) [tex]1.5*10^{-5}\ \frac{error}{piece}[/tex]
5) [tex]33.40\ \frac{points}{career\ playoff\ game}[/tex]
Step-by-step explanation:
1) Convert mixed numbers to decimal numbers dividing the numerator by the denominator and adding the result to Whole number part:
[tex]21+0.75=21.75\\\\2+0.5=2.5[/tex]
The unit rate is:
[tex]Unit\ rate=\frac{21.75\ meters}{2.5\ hour}\\\\Unit\ rate=8.7\ \frac{meters}{hour}[/tex]
2) Divide 2,857 points by 1,487 games:
[tex]Unit\ rate=\frac{2,857 \ points}{1,487\ games}\\\\Unit\ rate=1.92\ \frac{points}{game}[/tex]
3) Divide 255 strikeouts by 204 innings:
[tex]Unit\ rate=\frac{255\ strikeouts}{204\ innings}\\\\Unit\ rate=1.25\ \frac{strikeouts}{inning}[/tex]
4) Divide 15 errors by 1,000,000 pieces:
[tex]Unit\ rate=\frac{15\ errors}{1,000,000\ pieces}\\\\Unit\ rate=1.5*10^{-5}\ \frac{error}{piece}[/tex]
5) Divide 5,979 points by 179 career playoff games:
[tex]Unit\ rate=\frac{5,979\ points}{179\ career\ playoff\ games}\\\\Unit\ rate=33.40\ \frac{points}{career\ playoff\ games}[/tex]
