it is a method of estimation used in school e.g 698,656,675,689=700,700,700,700next step is to multiply 700 X 4=2800
4 x 0.05 = 0.2
40 x 5 = 200
4*5 = 20 so the answer should be around 20.
6 x 3 = 18
1, 2, 4, 8, 79, 158, 316, 632 all divide evenly into 632: 1 x 632 = 632 2 x 316 = 632 4 x 158 = 632 8 x 79 = 632
80 x 5 = 400
632
well, use cross multiplication 86/100=x/632 86*632=54352 54352/100 = 543.52 Therefore 86% of 632 is 543.52
7,836.8
632' x 25' = 15800 sq. ft.
40 x 20 = 800

D is 500, C is 100, X is 19 and I is 1. 632 is DCXXXII.
4 x 0.05 = 0.2
30 x 70 = 2100 30 x 73 = 2190
