50 x 10 = 500
50 x 0.1 is the same as 50/10 = 5
I would say that the easiest way is with proportions. Say you need to figure what percent of 10 is 5. 5 x _ = _ 10 100 10x=500 ______ 10 10 x= 50 what is 50% of 10 x 50 __ = __ 10 100 100x=500 ________ 100 100 x=5 5 is 50% of what 5 50 _ = __ x 100 50x=500 ________ 50 50 x=10
1 x 50, 2 x 25, 5 x 10, 10 x 5, 25 x 2, 50 x 1 = 50
50 = 1 x 50, 2 x 25, 5 x 10, 10 x 5, 25 x 2, 50 x 1
50 + 10% = 50 x (1 + 10/100) = 50 x 1.1 = 55 Therefore, adding 10 percent to 50 gives 55.
1 x 50, 2 x 25, 5 x 10, 10 x 5, 25 x 2, 50 x 1.
1 x 50, 2 x 25, 5 x 10, 10 x 5, 25 x 2, 50 x 1
50 x 10-3 = 0.05
