I am just going through a textbook on electronics and have come across an explanation that uses potential dividers to work out potential values for resistors. I was wondering if anyone is able to explain how the author got the bit after "which can be written as": R1=(4.9/10.1)*R2
How did he rearrange it to get this? Any help would be appreciated. Thank you! (I have added the pictures from the textbook.)
