63 21,3 7,3,3 3 x 3 x 7 = 63
Multiply 90 x .63= 56.7 is 63% of 90
x2-2x = 63 x2-2x -63 = 0 => x = -7 or x = 9 So x must = 9 Check: 92-18 = 63
because "of" means to multiply, you would just type 63% x 84 or convert 63% into a decimal and do .63 x 84 either way you would get 52.92
63 x 63 = 3969

72 To solve, set up 63/x=.875 and solve for x.
It is because... well lets work the problem and see what happens. 63 divided by 0.1 is 63 divided by 1/10. 63 divided by 1/10 is 63 multiplied by 10/1, or 10 63 x 10 is 630. Lets check if its correct. 630 x0.1 ------ 63.0 I hope it makes you understand.
63 x 63 = 3969
