6th grade math ratios 2

  1. 1. th 6 Grade Math Ratios # 2 Jessica Corriere & Robert Richards
  2. 2. Rio is having a pizza party for his friends. He is planning to order 3 large pizzas, each pizza has 8 slices. There will be 12 people, including Rio at the party. What is the ratio of pizza slices to people? A. 2:1 B. 24:8 C. 12:2 D. 3:8
  3. 3. Sometimes it is helpful to draw a picture of the problem
  4. 4. How to solve, The problem is asking for the number of pizza slices to people. Looking at the pictures, there are a total of 24 slices and 12 people. 24:12 is not one of the choices, but it can be seen that there are more pizza slices compared to people, so answers that have a smaller first number compared to the second number can be eliminated. Choice d can be eliminated because it has a smaller first number compared to the second number. The picture shows a pizza followed by 4 people, in 3 rows. That indicates one, 8 slice pizza for every 4 people. There is no answer choice of 8:4 but the ratio may be reduced by 4 if you divide both sides by 4. Once both sides were divided by 4 your answer will be 2:1, choice a. Check that by looking at a row of one 8-slice pizza and 4 people. If each of the 4 boys has one slice of pizza in their row, there are 4 slices left. That is enough for each boy to have another slice for a total of 2 slices each, 2:1 is the pizza slice to person ratio.
  5. 5. Common Core Standard 6th Grade 6.RP.1 Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. 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.”
