Answer:
n= 2/3m=6?
Step-by-step explanation:
So basically you use the ratio they have given you. You either multiply by 2 if image is enlarged or divide by 2 if it is reduced. (Keep in mind I got the 2 from your ratio : 1inch : 2inches) Therefore the find the original width, you multiply 10 by 2, giving you 20 inches.
Wouldnt you need it to equal something? like a-5=b so then b+5=a
