Since the quiz/test (or whatever it may be) is out of '40' we know that 40 out of 40 is 100%, or the full marks. Now, since we know that, we can divide 28 by 40. 28/40 = 0.7 After, we take this number and multiply it by 100 to make it equal to the percentage.. 0.7 x 100 = 70 So, 28 out of 40 is equal to 70%
28% of 40= 28% * 40= 0.28 * 40= 11.2
It is: 28/40 times 100 = 70%
To find the scale factor, divide the corresponding dimensions on the scale drawing by the actual dimensions. For the length, 40 ft is equal to 480 in, so the scale factor is 16 in / 480 in = 1/30. For the width, 28 ft 9 in is equal to 345 in, so the scale factor is 11.5 in / 345 in = 1/30. María used a scale factor of 1/30 in her drawing.
40 - 28 = 12
28 out of 40 is .7 or 7/10
