Answer: I think you have been going a bit crazy. Your school wants you to pass thro the process to try and find answers and solve them, Instead have outsoruced them. If this is way, it goes, all the jobs will land up in India… and you need to get to grazing cattle

Question: Math/Rational Numbers: Trouble with rationalizing the denominator?

I am having trouble with this picticular question:
3/Radical(12)

I get 3 Radical (12)/12 as my answer. According to my worksheet the answer is not correct.

Answer: You first need to reduce your fraction. Divide the top and bottom by 3. You end up with Radical(12)/4.
You can split your 12 into 3*4 so you have Rad(3*4)/4.
You can split the radicals so you have Rad(3)*Rad(4)/4.
Rad (4)=2, so you have 2*Rad(3)/4.
Reduce by dividing top and bottom by 2.
You end with Rad(3)/2.
