A tiny statue of Tom Brady is 2 8/15 inches tall If the statue uses a scale of 1 inch 2.5 feet, what is Tom Brady's actual height?
1 Answer
Explanation:
First, we can set up a proportion.
#(2 8/15 color(white)i "in")/ (color(red)x color(white)i "ft") = (1 color(white)i "in") / (2.5 color(white)i "ft")#
Now we can cross-multiply and solve for
#2 8/15 * 2.5 = 1 color(red)x#
#38/15 * 2.5 = color(red)x# #-># rewrite the mixed number as an improper fraction
#38/15 * 5/2 = color(red)x# #-># rewrite the decimal as an improper fraction
#cancel38^19/cancel15^3 * cancel5^1/cancel2^1 = color(red)x# #-># cancel
#color(red)x = 19/3#
#color(red)x = 6 1/3# #-># rewrite improper fraction as a mixed number
Tom Brady's height is
#1/3# of#1 color(white)i "ft" = 1/3 * 12 color(white)i "in" = 4 color(white)i "in"#
So, Brady's actual height is
