800 x 5 = 4,000
800
5/8*x=100 x=800/5 x=160
1/4 x 800 = 200 1/5 x 1000 = 200 They are the same. There is no difference.
800+800=1600 800$800=640000
800 x 5 = 4,000
5 x 800 = 4000

800 = 2 x 2 x 2 x 2 x 2 x 5 x 5
To find what percent of 800, 40 is: (40/800)x100 = .05 x 100 =5 40 is 5% of 800
5 x 8 = 40
2 x 2 x 2 x 2 x 2 x 5 x 5
5/8*x=100 x=800/5 x=160
Factor them. 3 x 3 x 5 = 45 2 x 2 x 2 x 2 x 2 x 5 x 5 = 800 Combine the factors, eliminating duplicates. 2 x 2 x 2 x 2 x 2 x 3 x 3 x 5 x 5 = 7200, the LCM
