70 x 1.4 ie 98. 40% of 70 is 28. If you add 28 to 70 the answer is 98.
-452
28% of 40= 28% * 40= 0.28 * 40= 11.2
40
39.2 Because 28 divided by 10 is 2.8 which is 10% 2.8 x 4 = 11.2 which is 40% Add them together and you get 39.2 (i think. my mental maths isn't amazing)
It is: 28/40 times 100 = 70%
40 - 28 = 12
28 out of 40 is .7 or 7/10
It is: (28/40)*100 = 70%
LCM of 28 and 40 = 280
