There's a calculation im really stuck on...and im not sure if im doing it properly:
im working out the percentage difference of netforce and (m1+m2+)a

so for my net force i have a value of 1.96, and for the (m1+m2)a i have a value of 0.3527 . Im not sure how to work out the percentage difference. So far ive gotten:
1.96 - 0.352 = 1.608

=1.608 / 1.96

= .8204 * 100

but i dont think this is right?

Looks OK - the diff is 82% of the net.
