A book cover is 8 inches by 10 1/4 inches. What are the dimensions of the cover when it was reproduced for a catalog picture using a 1/12 scale? Please show your work

Multiply 10 1/4 inches by 1/12. To make it easier, turn 10 1/4 into a mixed number by multiplying the 10 and the 4 and adding it to the 1.
41/4 x 1/12 = 41/48 (prime)
Now multiply 8 by 1/12. 
8/1 x 1/12 = 8/12 = 2/3 
The new dimensions are 41/48 inches by 2/3 inches. 
so essiensially the catalog legnth is 1/12 of the the acctuall legnth and the width is also 1/12 so accutall legnth=10 1/4 so catalog legnth=1/12 times 10 1/4 is 41/48 in accutual legnth=8in catalog legnth =1/12 times 8=8/12=2/3in so dimentions are 2/3 in by 41/48 in or 0.66in by 0.854 in
