Simplifying Rates and Ratios in Pre-Algebra

The video tutorial explains how to simplify the ratio of cans of soda to people. It starts by identifying the initial ratio of 92 cans to 28 people and aims to simplify it. The process involves finding the greatest common factor (GCF) of the two numbers by using prime factorization. The GCF is determined to be 4, and both numbers are divided by this factor to simplify the ratio to 23 cans for every 7 people. The tutorial concludes by discussing the interpretation of the simplified ratio.

What is the initial ratio of cans of soda to people?

• 92 cans of soda for every 28 people

• 46 cans of soda for every 14 people

• 14 cans of soda for every 46 people

• 28 cans of soda for every 92 people
