Hi all, really need some help with this!
I know it's super duper easy but I won't get this without a proper explenation, please help me
Okay so we are supposed to simplify this;
4a/5 * 15/2a
I think I know how to do it in theory but I just can't seem to get the right answer. Im thinking of inverting the first one and then multiplying the second one by 2 in order to get the same nominator, but it's still not right.
Just for the heck of it i'd like some help with this one aswell. It's the same thing - Simplify
2/9z * 3z^2/10
