\[\frac{1600000}{800}=\frac{16000}{8}=?\]

OpenStudy (anonymous):

i think for the first 1 A would be C: 2 M:20

OpenStudy (anonymous):

how did you get that @Anonymous1321

OpenStudy (zzr0ck3r):

you cant tell me what 16000 divided by 8 is?

OpenStudy (anonymous):

2000

OpenStudy (zzr0ck3r):

2000 = ? x 1000

OpenStudy (zzr0ck3r):

what is ?

OpenStudy (anonymous):

2

OpenStudy (zzr0ck3r):

1000 = 10 ^ ?

OpenStudy (zzr0ck3r):

what is ?

OpenStudy (anonymous):

3

OpenStudy (zzr0ck3r):

so \[\frac{1.6 \ million}{800}=\frac{1600000}{800}=\frac{16000}{8}=2000=2\times1000=2\times10^3\]

OpenStudy (zzr0ck3r):

understand?

OpenStudy (anonymous):

i think so. thank you

OpenStudy (zzr0ck3r):

let me know if there is anything you dont get.

1.A would be 2x10^25 sorry, well first find how many 0's both digits has then use scientific notation so 4x10^14 and 5x10^10 (4x5) = 20x10^14 and we can have 2 digits so its 2x10^25

OpenStudy (anonymous):

okay, thank you
