When multiplying tens or hundreds you can just multiply the first numbers:
1 x 8 = 8
and then add the zeros, so in this case you have two zeros after 1 and two zeros after 8, four zeros total, place those after the 8. . .
and the answer is 8,000
8 times 100 = 800
100 times because if you divide 4 into 800 you will get 100
8 x 12.5 = 100
8000 is 100 times larger than 80
It is: 520/800 times 100 = 65%
It is: 360/800 times 100 = 45%
100 x 8 = 800.
100 times greater
It is: (1500-800)/800 times 100 = 87.5% increase
It is: 320/800 times 100 = 40%
How about: 8 times 100 = 800 as one example
800 * 100 = 80000 of them.800 * 100 = 80000 of them.800 * 100 = 80000 of them.800 * 100 = 80000 of them.
