1. 20% since 5x = 100%
2. Simplify the following:
1/6×9/2×8/5
1/6×9/2×8/5 = (9×8)/(6×2×5):
(9×8)/(6×2×5)
The gcd of 9 and 6 is 3, so (9×8)/(6×2×5) = ((3×3) 8)/((3×2) 2×5) = 3/3×(3×8)/(2×2×5) = (3×8)/(2×2×5):
(3×8)/(2×2×5)
8/2 = (2×4)/2 = 4:
(3×4)/(2×5)
4/2 = (2×2)/2 = 2:
(3×2)/5
3×2 = 6:
Answer: 6/5
