Scale RATIO of a Drawing | 7.RP.A.1 💚💙

In this short math video we will determine the scale ratio of a drawing to answer a standardized math test question. We will begin by drawing a picture to visualize the problem. We will compare the drawing length to the actual length. We will write the scale as a ratio. We will simplify the ratio by dividing both sides of the ratio by the same value. We will select the correct answer choice. An exemplar solution is modeled and explained.
