How do I convert 325 degrees F to the appropriate metric unit? I just need to be lead through step by step, so that know in case of another question like this.

OpenStudy (calculusxy):

I am unclear with "to the appropriate metric units". But do you convert it to Celcius?

OpenStudy (anonymous):

I'm not sure. That's all it asks. Let me show you what it says exactly: Convert 325 degrees Fahrenheit to appropriate metric unit.

OpenStudy (calculusxy):

If you were to convert it to Celsius, then you would have to do: (Degree - 32) x 5/9

OpenStudy (anonymous):

Okay. I'll try it.

OpenStudy (anonymous):

Okay, so the (Degree-32) part I did 325-32, which is 293, but how do I multiply by 5/9?

OpenStudy (calculusxy):

293. 5 ---- X. --- 1. 9 Multiply horizontally

OpenStudy (anonymous):

Okay

OpenStudy (anonymous):

then i divide right?

OpenStudy (calculusxy):

Yes

OpenStudy (anonymous):

which would bring me to the answer 162.7777778

OpenStudy (calculusxy):

Please wait while I do the calculations.

OpenStudy (anonymous):

Okay

OpenStudy (calculusxy):

I did not get the same answer as yours.

OpenStudy (anonymous):

Oh. After I multiplied I got 1465/9. is that correct?

OpenStudy (calculusxy):

Yes

OpenStudy (anonymous):

Okay, and then I divided 1465 by 9 and got 162.7777778. Is that correct, or no?

OpenStudy (calculusxy):

Sorry my mistake. And yes, you're correct.

OpenStudy (calculusxy):

I think you should round this to the nearest whole number.

OpenStudy (anonymous):

Okay. Wouldn't that just be 162.7?

OpenStudy (calculusxy):

Well the one that you just said right now, would be to the nearest tenths, which may also be valid. Although, you're estimate is incorrect. Since five or above (7) you need to round above. Then, you would have 162.8 . By whole, I meant to work with the 2 of 162. You now look at the tenths place (7). Since seven is greater than 5, you round up. So 162 ~ 163 degrees Celsius.

OpenStudy (anonymous):

Oh. Okay, thank you very much for your help!

OpenStudy (calculusxy):

You're welcome :)
