What number plus one fourth of itself equals 560?
The easiest way to solve this problem is to turn it into an equation. The problem poses two unknowns which can be written as x and 1/4x (or 0.25x). We are told that the sum of x and 0.25x (=1.25x) = 560, so now we have an equation we can solve:1.25x = 560 ; now we divide both sides by 1.25 to get the value for xx= 560/1.25x = 448(1/4 of 448 = 112; 448 + 112 = 560; QED)Another way to solve this is to see the figures as percentages:x = 100%560 =125% (from the question we know that 560 is 1 1/4 times x, 1/4 is 25%)x = 560 x 100 ÷ 125x = 448(1/4 of 448 = 112; 448 + 112 = 560; QED)
What is the LCM of 16 28 and 64?
448
What is seven eighths of 64?
7/8 * 64= 448/8= 56====
What is the square root of 448 simplified as?
8√7. Since the square root of 4 is 2 you just keep dividing the number by 4 and multiplying 2 outside the radical until you get to a number not divisible by 4. (√448 = √[112*4] = 2√112) then (2√112 = 2√[28*4] = 4√28) then (4√28 = 2√[7*4] = 8√7)
What 2 numbers can you multiply to get 224?
448
