Calculate the range of these temperatures During one week in April, in Quebec, the daily minimum temperatures were
-5°C,
-1°C
3°C,
2°C
-2°C,
0°C,
6°C.

The ranger of temperature is 11 degree celcius. This is because to find the range of temperature of a specific place, you need to take the highest temperature to subtract the lowest temperature. Which in this case is: 6-(-5)=11

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
