A scanner scanned 56 photos in 7 minutes. If it scans photos at a constant rate, it can scan _____ photos in 27 minutes. Numerical Answers Expected! PLEASE HELP

Respuesta :

It can scan 216 photos in 27 minutes since the rate is 8 photos per minute.
Writing and solving an equation of two ratios would be one of the easier ways to solve this problem.

56 photos          x
-------------- = ------------
  7 min            27 min

x is found as follows:  (56 photos)(27 minutes) = (7 min)(x)

Divide both sides by (7 min) to get the answer, x, which is measured in "photos."
