Question

Consider these three numbers written in scientific notation: 6.5 × 10³, 5.5 × 10⁵, and 1.1 × 10³. Which number is the greatest, and by how many times is it greater than the smallest number?

Answer 1

Explanation:

First multiply the three scientific numbers individually.

6.5 x 10³ = 6,500

5.5 x 10⁵ = 550,000

1.1 x 10³ = 1,100

5.5 x 10⁵ is the greatest number.

Now find how many times greater is the larger number from the smaller number which is 1.1 x10³

5.5 x 10⁵
______ = 5x 10² = 500

1.1 x 10³

So, the largest number is 500 times greater than the lowest number.
