Final answer:
To find equivalent ratios to 1:2, multiply or divide both quantities in the ratio by the same non-zero number.
Step-by-step explanation:
Ratios are fractions that represent the relationship between two quantities. In this case, we are looking for ratios that are equivalent to 1:2.
To find equivalent ratios, we can multiply or divide both quantities in the ratio by the same non-zero number. For example, if we multiply both quantities by 2, we get 2:4, which is an equivalent ratio to 1:2.
Some other ratios equivalent to 1:2 include 3:6, 4:8, and 5:10.
