Since they are asking you to multiply 434 by 310, that is your first step.
434 x 310 = 134,540.
To make sure that this is the correct answer, you would divide 134,540 by 434 or 310 which would give you 310 or 434.
134,540 ÷ 434 = 310
or
134,540 ÷ 310 = 434
So the correct answer would be
134,540.
I hope this helps!
