turn it into a percent which is 70% then put the percent over 100
keep simplifying until you get 7/10
70= 35= 7
100= 50=10
28÷514=0.
514÷28=18.

5.6-4.9=x
.7= x is the answer not .8
9u means you're multiplying 9 into that vector, both components. Same with the 2v. 9*3 = 27 and 9*-1 = -9, so your new vector u is <27, -9>. Now let's do v. 2* -6 (twice) = -12, so your new v vector is <-12, -12>. Add those together now, first components of each and second components of each. 27 + (-12) = 15; -9+(-12)=-21. So the addition of those gives us a final vector with a displacement of <15, -21>
