Hello there! Your answer is <em>B) 56</em>.
To solve this problem quickly, we can use estimation.
To do this round 117 to the nearest 10 - 120 and 2.1 to 2.
Now we have 120 ÷ 2.
Okay, so we know 12 ÷ 2 is 6, so just take that and add a zero on the end since there's an extra 0 in 120.
120 ÷ 2 = 60
The closest answer to this is b, and since we used estimation, B is your exact answer.
I hope this helped and have a great rest of your day! :)
