Well you can divide by 20 so to get to 300 15 people counted because 300/20=15 and to get to 600 30 people counted because 600/20=30
It depends on what tax is.
To mutply fractions you just mutpily across so 2/3*3/4 would equal 6/12 or 1/2 because 2*3=6 and 3*4=12
40*4=160
30*30 or you can do 3*3=9 then add the 2 zeroes to the end=900=30*30
6x*3=18x b/c you can't simplify any further then that
13. Here's the equation for it: 126*.159*2/12
14. Here's the equation:(1050*.119*.5)+1050
SOLVE them
Assuming you are asking how many servings per a package then 24/9 = 2.6666666666666667
Well 216/6=36 so sqrt of 36 is 6 b/c 6*6=36
