Answer :
To check if two ratios are equivalent, you can simplify both ratios to their simplest form and see if they are the same.
For the ratio 4:18:
- Divide both numbers by their greatest common divisor, which is 2.
- 4 ÷ 2 = 2
- 18 ÷ 2 = 9
So, the simplified ratio is 2:9.
For the ratio 1:2:
This ratio is already in its simplest form.
Comparing the simplified ratios:
- 2:9 ≠ 1:2
Therefore, the ratios 4:18 and 1:2 are not equivalent.
