To express the number 0.045 as a percent, follow these steps:

1. Understand that "percent" means "per hundred". Thus, converting a decimal to a percent involves determining how many parts out of 100 the decimal represents.

2. To convert a decimal to a percent, multiply the decimal by 100. Mathematically, this is represented as:
[tex]\[ 0.045 \times 100 = 4.5 \][/tex]

3. The result from the multiplication is 4.5. Therefore, 0.045 as a percent is 4.5%.
