Answer 1

The correct option is A

more than $2$ times greater

Celebrity A has about $8.6\times {10}^6$ followers.

Celebrity B has about $4.1\times {10}^6$ followers.

Estimate for the number of followers for Celebrity A compared to the number of followers for Celebrity B = $\frac{8.6\times {10}^6}{4.1\times {10}^6}$
