x % of 80 = 20 = x / 100 x 80 = 20 = 8 x / 10 = 20 = x = 20 x 10 / 8 = x = 25% (answer)
80/x = 8/20 Taking reciprocals of both sides, x/80 = 20/8 Multipling both sides by 80, x = 80*20/8 simplifying: x = 20*80/8 = 20*10 = 200.
20 x 80= 1600
4 times 20 = 80
80 x 0.25 = 20
x % of 80 = 20 = x / 100 x 80 = 20 = 8 x / 10 = 20 = x = 20 x 10 / 8 = x = 25% (answer)
80
80/x = 8/20 Taking reciprocals of both sides, x/80 = 20/8 Multipling both sides by 80, x = 80*20/8 simplifying: x = 20*80/8 = 20*10 = 200.
four 20 of 4 is 80 20 x 4 = 80
20 x 80= 1600
25% of 80 is 20. (0.25 x 80 = 20)
2 x 2 x 5 = 20 2 x 2 x 2 x 5 = 80 2 x 2 x 5 = 20, the GCF 20/80 = 1/4
80 = 1 x 80 80 = 2 x 40 80 = 4 x 20 80 = 5 x 16 80 = 8 x 10
YES!!! 4 x 20 = 80
20/80 x 100 = 25%
80 x 20 = 1600.
x2+16x-80 = 0 (x-4)(x+20) = 0 x = 4 or x = -20
