\[\frac{ 4y }{ 5x } * \frac{ x }{ 8y }\]

OpenStudy (anonymous):

Multiply straight across

OpenStudy (anonymous):

You get (4yx)/(40xy)

OpenStudy (anonymous):

Which is the same thing as (xy)/(10xy)

OpenStudy (anonymous):

Which is the same thing as 1/10

OpenStudy (albert0898):

I'm doing it a different way. I crossed out the factors. I got \[\frac{ 1 }{ 5x } * \frac{ x }{ 2 }\]

OpenStudy (anonymous):

You still have to multiply

OpenStudy (albert0898):

Then simplifying that... 1/4x * 1/2

OpenStudy (anonymous):

When you have 1/2 times 1/2, you have to multiply straight across to get 1/4

OpenStudy (albert0898):

In the end I got 1/8x , is that right?

OpenStudy (anonymous):

No. If you have (1/5x)x(x/2), you have to multiply the numerators and denominators (multiplying straight across.)
