One eighth of 40 is 5. So 5 eighths of 40 = 5 x 5 = 25.
If 81% of x is 3 then x*81/100 = 3so x = 3*100/81 = 100/27 = 3.703703...If 81% of x is 3 then x*81/100 = 3so x = 3*100/81 = 100/27 = 3.703703...If 81% of x is 3 then x*81/100 = 3so x = 3*100/81 = 100/27 = 3.703703...If 81% of x is 3 then x*81/100 = 3so x = 3*100/81 = 100/27 = 3.703703...
40/81 is in its simplest form.
81 = 1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1.
81 = 1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1
-81
1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1 = 81
1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1
1, 3, 9, 27, 81. 1 x 81 = 81, 3 x 27 = 81, 9 x 9 = 81.
1 x 81, 3 x 27, 9 x 9 = 81
