Lesson 22 Redrawing a Scale Solutions and Step by Step Guide

To effectively solve problems involving scaling, follow these steps:

First, identify the ratio or proportion given in the problem. This ratio will guide you in adjusting the size of the drawing or object. For example, if you’re asked to make a drawing 1/2 the size of the original, apply that ratio to all dimensions.

Next, calculate the new measurements based on the given ratio.

If the original measurement of an object is 12 cm and the scale is 1:4, the new measurement will be 12 cm divided by 4, giving you a scaled measurement of 3 cm. Repeat this for each dimension–length, width, height, etc.–to complete the transformation.

Finally, double-check your work.

It’s important to verify that your scaled drawing is proportional and aligns with the given ratio. Cross-reference your measurements to ensure the accuracy of your results. By practicing these steps, you’ll enhance your ability to manipulate ratios and dimensions with precision.
