Cost/(number of cassettes) = $14.50/2 = x/15
Multiply by 15 to solve
15*($14.50/2) = x = $108.75
15 cassettes will cost $108.75.
When you see the fraction 33/16, you realize that 33 divided by 16 is 2 remainder 1, so you add the 2 to the original 6, then put the remainder 1 on top of 16 ,which gives you 8 1/16
6x - 2x = 16
4x = 16 |divide both sides by 4
<h3>x = 4</h3>
1:4 and 6:24 because 3/3=1 and 12/3=4 and 6/2=3 and 24/2=12
4 because 2cups of 1/2 cups=1cup
2x2=4
