15% of 240 is 36 Let x be the quantity we are looking for So to find this using a proportion, look at 15/100=x/240 so 100x=15x240 and x=36
The distributive property is not used for simplified multiplication. See http://www.algebrahelp.com/lessons/simplifying/distribution for information about how to use the distributive property to simplify other equations. 20 x 12 is already simplified, so the proper way to solve it is 12 x20 ----- 240 You could potentially factor and use the commutative property to find a simpler equation, ex. 20x12 -- break 20 into 10 and 2 10x2x12 -- multiply 2 by 12 10x24 -- multiply by 10 240

You would use square metres (m2) to find the area of a door.
people use pi to find the circumference of a circle.
Yes! You can express this as a function, like this: In my example I will say that the salary is $240.00 and this is based on a standard 30 hours of training. g(x)=30x +240 What we are basically saying is that whatever number we plug in for g(x) would determine how much they are paid. For example if we add 20 times the amount of hours of training we would get g(20)=30x + 240 Then plug in 20 for our x 30(20) +240 the new salary would be $840 :)
8 is what percent of 64:= 8 / 64= 0.125Converting decimal to a percentage:0.125 * 100 = 12.5%
x+y = 240 0.06x + 0.12y =240(0.07) = 16.8 0.06x + 0.12(240 - x) = 16.8 0.06x + 28.8 - 0.12x = 16.8 -0.06x = -12 x = 200.......6% solution y = 40........12% solution
Why don't you use a calculator? 4000 x0.06 = 240 PerCent is; of a century, which is 100. So 6 percent is: 6 parts of 100 or: 6 divided by 100
