Answer: He needs to answer 20 mails.

Step-by-step explanation:

Given : Mr. Kelly answered seven emails. This is 35% of the emails he must answer.

We can write 35% as 0.35. [To convert percent into decimal , we divide it ny 100.]

Let x be the number of mails that must be answered.

Then, according to the question we have,

$0.35x=7$

Divide both sides by , we get

$x=20$

Hence, he needs to answer 20 mails.
