ratio table
A table listing pairs of numbers that form equivalent ratios.
A ratio table is a tool used to compare two quantities or values in a proportional relationship. It is a way to organize information in a table format, typically with two columns, to highlight the relationship between the quantities.
To create a ratio table, first identify the two quantities being compared, and then choose a common unit of measure for them. For example, suppose we want to compare the number of apples and oranges in a basket. We can use the common unit of fruit to represent both apples and oranges:
| Fruit | Amount |
|——–|———-|
| Apples | x |
| Oranges| y |
Next, establish the proportion between the two quantities. This can be done by either calculating it, or by using the given information. Let’s suppose the ratio of apples to oranges is 3:2:
| Fruit | Amount |
|——–|———-|
| Apples | 3x/5 |
| Oranges| 2x/5 |
In this example, the ratio table shows that for every 3 apples, there are 2 oranges in the basket. We can also use the table to find the total number of fruit in the basket by adding the two amounts:
Total fruit = 3x/5 + 2x/5 = 5x/5 = x
Therefore, there are x fruits in the basket, with 3/5 of them being apples, and 2/5 of them being oranges.
