  • Thanks bro

  • @hendrix5045 I know how to deal with fractions but I can't put the slash key on the comments

  • @BobxLovesxMuffins , that's a joke right? What an idiotic thing to say. The reason I asked if you did it with a calculator I thought would be obvious but I guess not so I'll have to spoon feed you lol. Typically, when someone doesn't know how to deal with fractions they use a calculator, which unless it's a TI-model it will give you decimals. Also if you were in a real math class using decimals would be counted against you because it would be obvious you don't know how to deal with fractions.

  • @hendrix5045 I didn't use a calculator

    maybe you think I used a calculator because you can't do it without one

    are you impressed dumbfuck?

  • @BobxLovesxMuffins, lol did you use a calculator? Decimals aren't impressive bro :P

  • Wait towards the end wen u did (radical)41 over (radical)16 and u reduced it to (radical)4, don't u also hv to multiply (radical) 4 to the numerator to get (radical)164 over 4? I'm not sure tho:/

  • thank you very very very very much.
