**Ms. Sue**, Sunday, March 24, 2013 at 3:19pmC = 5/9(F-32)

C = (5/9) (11 - 32)

C = 5/9 (-21)

C = -105/9

C = 11.67

**Eric**, Sunday, March 24, 2013 at 3:39pmTHE TEMPERATURE ON A SUMMER DAY IS 77 DEGREES FAHRENHEIT.the formula to convert the temperature to degrees Celsius is C = 5/9(F-32) what is the corresponding temperature in degrees Celsius?

Sorry Ms. Sue I cut of the top of the screenshot, it is 77 degrees Fahrenheit.

**Ms. Sue**, Sunday, March 24, 2013 at 3:45pmUse the same method I used, except substitute 77 for 11.

**Eric**, Sunday, March 24, 2013 at 4:29pmSo I did what you said but I am not sure how you got to C= 5/9(-21)

to C=105/9

So on mine C=(5/9)(77-32)

I got C=5/9(-45)

I am unsure how you did the math to come to your C=-105/9 answer and then the C=11.67 answer. Please show me those last steps if you do not mind, Thanks for all the help.

**Ms. Sue**, Sunday, March 24, 2013 at 4:47pmC = 5/9 (-21) I subtracted 32 from 11 (the degrees F).

C = -105/9 I multiplied 5/9 times -21

C = -11.67 I divided the numerator by the denominator

When the temperature is 77 degrees F, it is 25 degrees C.

Work with the formula until you get 25 degrees C.
