Marta is solving this problem.                                     434                               × 310   what are the partial products marta will need to find the product?

What are partial products? if you mean the product of the answer its 134,540

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!
