The factors of 480 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, and 480. The factor pairs of 480 are 1 x 480, 2 x 240, 3 x 160, 4 x 120, 5 x 96, 6 x 80, 8 x 60, 10 x 48, 12 x 40, 15 x 32, 16 x 30, and 20 x 24.
Let label one of the numbers with x, and the other one with y. So, xy = -240 x + y = 8 y = 8 - x substitute this into the first equation; x(8 - x) = -240 8x - x^2 = - 240 -x^2 + 8x + 240 = 0 or multiplying by -1 both sides; x^2 - 8x - 240 = 0 (x + 12)(x - 20) = 0 x + 12 = 0 or x - 20 = 0 x = -12 or x = 20 So these numbers are -12 and 20. Check: -12 + 20 = 8 (-12)(20) = -240
The product of 8 and 30 is 240.
2/3 of 240 = 2/3 x 240 = 2x240/3 = 160
I'm no expert but I'm guessing this may help you... odd x odd = odd even x even = even odd x even = even for negatives and positive multiplying... n x n = p p x p = p n x p = n i hope this helps you! another thing that works is halving and doubling for example: 16x15=240 8x30=240 4x60=240 2x120=240 1x240=240
60 x 240 = 14400 60% x 240 = 144
60 x 4 = 240
four 240 is 4 of 60 60 x 4 = 240
4 x 60 = 240
60 x 4 = 240
240/60 x 100 = 400 percent.
60 x 4.0 = 240 60 x 0.1 = 6 240 - 6 = 234
60/25 x 100 = 240 Therefore, 60 is 240 percent of 25.
25% of 240 = 0.25 x 240 = 60 0.30 of 240 = 0.30 x 240 = 72 therefore, 0.30 of 240 > 25% of 240
1 x 240, 2 x 120, 3 x 80, 4 x 60.
240 because... 6 x 40 = 240 4 x 60 = 240
60 times 4 is 60 x 4 = 240
