**Ratios and Proportions** – Free printable worksheets covering sixth grade ratio and proportion standards.

*Understand ratio concepts and use ratio reasoning to solve problems.*

*For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”*

**CCSS.Math.Content.6.RP.A.2 –**Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship.

*For example, “This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar.” “We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger.”*

**CCSS.Math.Content.6.RP.A.3 –**Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.

**CCSS.Math.Content.6.RP.A.3.a –**Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.

**CCSS.Math.Content.6.RP.A.3.b**– Solve unit rate problems including those involving unit pricing and constant speed.

*For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?*

**CCSS.Math.Content.6.RP.A.3.c**– Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.

**CCSS.Math.Content.6.RP.A.3.d**– Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
