The bacteria is about 6.67 * 10⁻³ smaller than the amoeba cell
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
The length of a bacterial cell is about 3 x 10⁻⁶ m, and the length of an amoeba cell is about 4.5 x 10⁻⁴ m, hence:
Ratio of bacteria to amoeba = 3 x 10⁻⁶ m / 4.5 x 10⁻⁴ m = 6.67 * 10⁻³
The bacteria is about 6.67 * 10⁻³ smaller than the amoeba cell
