First, let's write an expression to represent this:

Now we'll simplify it:
60 would round 61.59 which is what you get when you divide those two numbers. I hope I helped
Divide the whole numbers:
2 / 5 = 0.40
When dividing scientific numbers subtract the exponents:
10-6 = 4
Now you have:
0.4 x 10^4
Rewrite to scientific notation:
4 x 10^3
Convert to standard form: 4000
The answer is A.
