Answer
I'll set them up and you can do the arithmetic
1) 1/20 = x/240, solve for x
2) 298000000(0.067) =
3) I can't draw graphs for you.  You can find the number of degrees for each part by multiplying 360 by the fraction, such as 360(0.45).  Then use a protractor to do your circle graph.
4) interest = 550(1.06^6 -1)
5) 600 = x(1.06^5 -1) solve for x
6) let x = no. of cassettes
8x = 10(8x) = 704, solve for x
7) (1500-1200)(100)/1500 = % decrease
8) 48(0.6) =
9) 16500(1.04) =
10) 1/4
11) 105/150 =
12) (1/2)(1/6) =
13) 6/16 = 3/8
