Athermometer shows that the outdoor temperature is 40 degrees celsius. use the formula f=(9/5)c+32 to find the temperature f in fahrenheit.

Insert 40 for c in the formula;   (9/5)times40 which gives you 72, and then add 32 to that to give you your answer of 104.

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.
