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
To find the diameter of a circle when given the circumference, you can use the formula: circumference = π * diameter. In this case, the circumference is 240cm. So, 240 = π * diameter. To solve for the diameter, you divide both sides by π, giving you diameter = 240 / π ≈ 76.39 cm. Therefore, the diameter of the circle is approximately 76.39 cm.
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.
8 is what percent of 64:= 8 / 64= 0.125Converting decimal to a percentage:0.125 * 100 = 12.5%
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
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
