Ratios and Proportions in Recipes

Mrs. Nelson introduces a lesson on representing ratios with tables, using a trail mix recipe as an example. She explains how to calculate equivalent ratios by adjusting the quantities of almonds and raisins for different batch sizes. The lesson emphasizes maintaining the same flavor by using proportional amounts of ingredients. The video concludes with a summary of the key concepts and the ability to use tables to find equivalent ratios.

What is the main objective of using tables in this lesson?

• To determine the cooking time

• To measure the nutritional value

• To calculate the cost of ingredients

• To find equivalent ratios

In the trail mix recipe, how many ounces of almonds are used in one batch?

• 7 ounces

• 5 ounces

• 12 ounces

• 10 ounces

What is the ratio of almonds to raisins in the original recipe?

• 1:1

• 2:3

• 7:5

• 5:7

If you have 28 ounces of almonds, how many ounces of raisins do you need to maintain the ratio?

• 20 ounces

• 14 ounces

• 25 ounces

• 10 ounces

When the raisins column shows 10 ounces, how many ounces of almonds are needed?

• 28 ounces

• 14 ounces

• 7 ounces

• 21 ounces

How do you determine the number of batches made when the almonds column shows 28 ounces?

• By dividing by 5

• By multiplying by 2

• By dividing by 7

• By adding 7

How do you adjust the quantities for a half-size batch of trail mix?

• Double the quantities

• Use the same quantities

• Divide the quantities by two

• Add five ounces to each ingredient

What is the amount of raisins needed for a half-size batch?

• 2.5 ounces

• 3 ounces

• 5 ounces

• 1 ounce

What is the purpose of using a table to represent ratios?

• To find equivalent ratios by adjusting batch sizes

• To determine the shelf life of the mix

• To list all possible ingredients

• To calculate the total weight of the mix

How can you move up and down the table to find equivalent ratios?

• By guessing the quantities

• By using a calculator

• By randomly selecting numbers

• By thinking about how many times bigger or smaller each part is
