Grade 8 - Number

Standard 8.N.4 - Find the unit rate to solve the equation.

Included Skills:

Demonstrate an understanding of ratio and rate.

• Express a two-term ratio from a context in the forms 3:5 or 3 to 5.

• Express a three-term ratio from a context in the forms 4:7:3 or 4 to 7 to 3.

• Express a part-to-part ratio as a part to whole ratio (e.g., Given the ratio of frozen juice to water is 1 can to 4 cans, this can be written as 1/4 or 1:4 or 1 to 4, [part-to-part ratio]. Related part-to-whole ratios are 1/5 or 1:5 or 1 to 5, which is the ratio of juice to solution, or 4/5, or 4:5 or 4 to 5, which is the ratio of water to solution).

• Identify and describe ratios and rates from real-life examples, and record them symbolically.

• Express a rate using words or symbols (e.g., 20 L per 100 km or 20 L/100 km).

• Express a ratio as a percent, and explain why a rate cannot be represented as a percent.
