here is your answer...

Answer 2

Answer: He needs to answer 20 emails.

Explanation:

Given : Jim has answered 7 e-mails . (1)

This is 35% of the e-mails he must answer .

We can write 35% as 0.35.

Let x be the number of emails he need to answer.

Then, Number of mails he has answered = 0.35x (2)

From (1) and (2), we have

`0.35=7\\\\\Rightarrow\ x=(7)/(0.35)=(700)/(35)=20`

Hence, he needs to answer 20 emails.
