Matching a Model with a Ratio

Several methods are used to represent ratios:
Writing a ratio as a fraction is the most commonplace method. For example \(\frac{2}{7}\)
Writing a ratio using the word “to” as in 5 to 9.
Writing a ratio using a colon in between the two numbers, 8:16.

Matching a Model with a Ratio – Examples 1, 2

Match each ratio to a correct model.
1) 4:6
2) 2:4
3) 1:6

Solution:
Step 1: Count the number of circles and squares in model a and write them as a ratio. 1:6
Step 2: Count the number of stars and squares in model b and write them as a ratio. 4:6
Step 3: Count the number of squares and circles in model c and write them as a ratio. 2:4
Step 4: Now match the ratio to the model.
1) b, 2) c, 3) a
