Step-by-step explanation:
A unit rate describes units of one quantity in accordance to one unit of other quantity.
1. 414 centimeters of snow in 23 hours
23 hours = 414 centimeters
Dividing both sides by 23
[tex]\frac{23}{23}=\frac{414}{23}\\1\ hour = 18\ centimeters[/tex]
Unit rate is 18 centimeters of snow per hour.
2. 126 customers in 9 checkout lanes
9 checkout lanes = 126 customers
Dividing both sides by 9
[tex]\frac{9}{9}=\frac{126}{9}\\1\ lane = 14\ customers[/tex]
Unit rate is 14 customers per checkout lane.
3. 273 cherry pieces in 7 bags of candy
7 bags = 273 cherry pieces
Dividing both sides by 7
[tex]\frac{7}{7}=\frac{273}{7}\\1\ bag = 39\ cherry\ pieces[/tex]
Unit rate is 39 cherry pieces per bag.
4. 36 dollars for mowing 2 lawns
2 lawns = 36 dollars
Dividing both sides by 2
[tex]\frac{2}{2}=\frac{36}{2}\\1\ lawn=18\ dollars[/tex]
Unit rate is 18 dollars per lawn.
5. 90 dollars for 45 tv channels
45 tv channels = 90 dollars
Dividing both sides by 45
[tex]\frac{45}{45}=\frac{90}{45}\\1\ channel=2\ dollars[/tex]
Unit rate is 2 dollars per tv channel.
6. 322 points for defeating 46 enemies
46 enemies = 322 points
Dividing both sides by 46
[tex]\frac{46}{46}=\frac{322}{46}\\1\ enemy=7\ points[/tex]
Unit rate is 7 points for defeating 1 enemy.
