Thread: multiply by reciprocal

To get rid of the 1/2 how is it done?

2d+4c=1/2 4b+2a

is it

2/1(2d+4c)=2/1(1/2 4b+2a)
so
4d+8c=4b+2a

or

2/1(2d+4c)= (2/1)1/2 4b+2a
so
4d+8c=4b+2a

or something different?

Thanks for any help you have.

Hello bentwoodbc,

I guess I'm unsure what you mean. Is this the problem



if so you can use the distributive law to simplify





if it is just

Good luck.
