Answer: 20 times

Step-by-step explanation:

Given : The length of a parasite in experiment A = 2.5\times10^{-3}\text{ inch}

The length of a parasite in experiment B = 1.25\times10^{-4}\text{ inches}

Then, the number of times the length of the parasite in experiment A is greater as compared to the length of the parasite in experiment B:-

n=\dfrac{2.5\times10^{-3}}{1.25\times10^{-4}}\\\\=\dfrac{2.5}{1.25}\times10^{-3-(-4)}\\\\=2\times10^{-3+4}=2\times10^{1}=20

Hence, the length of the parasite in experiment A is 20 times greater as compared to the length of the parasite in experiment B

We have been given that :-

The length of a parasite in experiment A is 2.5 \times 10^{-3}

The length of a parasite in experiment B is 1.25 \times 10^{-4}

Let us write the the  length of the parasite in experiment A in the exponent of -3.

1.25 \times 10^{-4}= 0.125 \times 10^{-3}

Clearly, the length of parasite in experiment A is greater than the length of parasite in experiment B.

The difference in the length is given by

2.5 \times 10^{-3} -0.125 \times 10^{-4}

=2.375 \times 10^{-3}

Therefore, the length of the parasite in experiment A is =2.375 \times 10^{-3} inches  greater than the length of the parasite in experiment B.
