Question

# The length of plant cell A is meter. The length of plant cell B is 0.000004 meter. How many times greater is plant cell A’s length than plant cell B’s length.

Hint:

### Write both the lengths as the same powers of base 10 and then compare.

## The correct answer is: 20

### Complete step by step solution:

Length of plant A cell =

Length of plant B cell = 0.000004m

On dividing length of plant A by plant B, we have

(write both numerator and denominator as same powers of base 10)

On cancelling 10^{-6} on numerator and denominator, we have

Hence, the length of plant A cell is 20 times greater than the length of plant B cell.
