9 out of 20 = 9/20 = 9 ÷ 20 = 0.45: 0.45 x 100 = 45%
Subtract 9 from each side. ( subtraction; both sides ) X + 9 = 20 X + 9 - 9 = 20 - 9 X = 11 -----------------check in original equation 11 + 9 = 20 20 = 20 checks
8/20, 7/20, 6/20, 6/20 etc, and 9/21, 9/30, 9/40, 9/50, 9/100, 9/1000 etc
The GCF of 9 and 20 is 1
9/20? Thats 0.45
20 = 0.45

9 percent of 20 = 1.89% of 20= 9% * 20= 0.09 * 20= 1.8
9 out of 20 = 9/20 = 9 ÷ 20 = 0.45: 0.45 x 100 = 45%
9 9/20
It is 9/20
9/20 as a percentage = 100*9/20 = 45%
9 over 20:= 9/20 in fraction
11/20 divded by 9/20 = 11/9
20/x = 9 Divide each side by 20. you get 1/x = 9/20. flip both sides. you get x = 20/9
Subtract 9 from each side. ( subtraction; both sides ) X + 9 = 20 X + 9 - 9 = 20 - 9 X = 11 -----------------check in original equation 11 + 9 = 20 20 = 20 checks
(20/5)/(20/9) is the same as (20/5)X(9/20) This can be reduced to (1/5)X(9/1) 9/5.
