I really suck at math?
16) -2/3 = 1/9(k)
If anybody can help me with these it would be a big help
14) -7/8(r) = 3/4
12) -3/8(t) = 0
8) -b + 3 - 1 = 3(4)

16) k=(-2/3)(9/1) k=-18/3 k= -6
14) r=(3/4)(8/-7) r=24/28 12/14= 6/7
12)t=0
8) -b=12+1-3 -b=11 b=-11
5)m=-2/3-1/5 m=-10/15-3/15 m=-13/15

16) So for this one, it works out well if you multiply both sides by 9 to get rid of fractions (they suck).
=> (-2/3)(9) = (1/9)(9)(k)
=> k = -6
14) Same idea, just multiply by 8 to clear out the denominators and DESTROY ALL FRACTIONS!!
=> -7(r) = 6
=> r = -6/7
12, 8, 6) Try eliminating fractions in these, too! Hint for 6), the smallest common denominator is 15. You can easily find this by simply multiplying the two denominators together => 3*5 = 15. Just multiply both sides by 15, and BOOM, you've gone from having to deal with fractions (bullshit) to just addition/subtraction (hallelujah).
