Understanding Ratios and Proportions

The video tutorial reviews equivalent ratios using a tuna casserole recipe. It explains how to maintain the same taste by adjusting ingredient quantities proportionally. The lesson covers writing ratios as fractions, calculating batch sizes, and verifying equivalent ratios. Students learn to create new equivalent ratios and understand their properties.

What happens to the taste of the casserole if you double all the ingredients?

• The taste changes completely.

• The taste remains the same.

• The taste becomes sweeter.

• The taste becomes saltier.
