john intended to place a mark 2 1/4 inches from one end of a narrow end 9 1/4 inches long, but he mistakenly placed the mark 2 1/4 inches from the other end. How far, in inches, is his mark from the location where he intended to place it?
A) 7
B)4 3/4
C)2 1/4
D)5
E)5 1/4
Solution
total lenght is 9 1/4 and john need to put the mark at 2 1/4 form the end.
so 9 1/4 - 2 1/4 = 7
That is actual mark should be at 7 inches.
The mark was put in 2 1/4,
so 7- 2 1/4 = 4 3/4
