Best ResponseYou've already chosen the best response.1The LCD is finding the smallest denominator that makes them both the same.

Best ResponseYou've already chosen the best response.1Do you have any ideas of how to start doing that?

Best ResponseYou've already chosen the best response.1If we multiply the left one by 2, we get a common coefficientdw:1433440278787:dw

Best ResponseYou've already chosen the best response.1Do you see how that gives us a common coefficient of 6?

Best ResponseYou've already chosen the best response.0yes, because 2 times 3 is 6?

Best ResponseYou've already chosen the best response.1And we have 2 x's on the left, but only 1 on the right.

JoannaBlackwelder
 one year ago
Best ResponseYou've already chosen the best response.1So we need to multiply the right side by x to make the number of x's the same

Best ResponseYou've already chosen the best response.1:) How do you think we can make the number of y's the same?

JoannaBlackwelder

Best ResponseYou've already chosen the best response.1Close. That would give us:dw:1433440631552:dw

JoannaBlackwelder

Best ResponseYou've already chosen the best response.1So the numbers of y's still aren't quite the same.

JoannaBlackwelder
 one year ago
Best ResponseYou've already chosen the best response.1It looks like we have 2 y's on the left, but 3 on the left.

Bananas1234

Best ResponseYou've already chosen the best response.0you mean 3 on the right?

JoannaBlackwelder
 one year ago
Best ResponseYou've already chosen the best response.1Yeah, sorry.

JoannaBlackwelder

Best ResponseYou've already chosen the best response.1So, we need one more y on the left.

Best ResponseYou've already chosen the best response.1Yep, great! So, are the denominators the same now?

JoannaBlackwelder

Best ResponseYou've already chosen the best response.1Great! So, in the full problem, how do we make that both denominators?

Best ResponseYou've already chosen the best response.1But we can't just change the denominators. We have to also change the numerators to keep everything balanced.

Best ResponseYou've already chosen the best response.1Was that all?

JoannaBlackwelder

Best ResponseYou've already chosen the best response.1No, dw:1433442752287:dw so we need to multiply the left fraction on top and bottom by 2y^2

Best ResponseYou've already chosen the best response.1Sorry, I was doing some online tutoring. But no, we didn't multiply by 2y^2 on the right fraction to get the LCD.

Best ResponseYou've already chosen the best response.1So, now we can subtract the numerators, and the denominators stay the same.

JoannaBlackwelder

Best ResponseYou've already chosen the best response.1So, what does that give us?

JoannaBlackwelder

Best ResponseYou've already chosen the best response.1No, I mean for the whole fraction.
