If you mean 7% of 400 then it is 28
The answer is 28.
28/5 x 7/4 28/5 (4) x 7/4 (5) 112/20 x 35/20 = 3920/400 3920/400 reduces to 9 4/5.
400% of 28 = 400% * 28 = 4 * 28 = 112
Set up your equation 28/x = 112/100 (that's 28 divided by x = 112 divided by 100). Then you can cross-multiply (giving you 2800 = 112x) and solve for x (which in this case is 25).
400 = 1 x 400 400 = 2 x 200 400 = 4 x 100 400 = 5 x 80 400 = 8 x 50 400 = 10 x 40 400 = 16 x 25 400 = 20 x 20
28% of 400 = 28% * 400 = 0.28 * 400 = 112

4003 = 400 x 400 x 400 = 64000000
About 28.28 ft. You can solve this as a right triangle problem. Multiply each side x itself (square it) that Is 400. Add the squares of the two sides (400+400= 800). Then find the square root of 800, which is 28.28
400/28=200/14=100/7
x * 1600 = 400 x = 400 / 1600 x = 1/4 x = 25% ■
1 x 28 = 282 x 28 = 563 x 28 = 844 x 28 = 1125 x 28 = 1406 x 28 = 1687 x 28 = 1968 x 28 = 2249 x 28 = 25210 x 28 = 280
If you mean 7% of 400 then it is 28
