The pairs of numbers that are equivalent are 0.04 and 4% and 0.4 and 40%.

Here's why:

1. 0.04 and 4%: To convert a decimal to a percentage, you multiply by 100. So, 0.04 * 100 = 4%. Therefore, these two are equivalent.

2. 0.04 and 400%: 0.04 * 100 = 4%, not 400%. Therefore, these two are not equivalent.

3. 0.4 and 40%: 0.4 * 100 = 40%. Therefore, these two are equivalent.

4. 0.4 and 4%: 0.4 * 100 = 40%, not 4%. Therefore, these two are not equivalent.
