Answer:
The answer to your question is 9
Explanation:
Data
Paramecium's length = 4.2 x 10⁻⁴ m
Ant's length = 3.8 x 10⁻³ m
Process
If we need to know how much longer is the ant than the paramecium, we just need to divide the ant's length by the paramecium's length.
Times that the length of the ant is longer than the paramecium length =
Simplification and result
9
