On the blueprint of Lauren's new office building, the scale is 3 in. equals 8 ft. What will be the actual length of Lauren's office if it measures 6 in. long on the blueprint?

3/6=8/x
solve for x. 
how do i solve for x

would the answer be 16ft?

cross multiply to solve for x
3/6 = 8/x
3*x = 6*8
3x = 48
x = 48 /3 = 16
