your answer would be 

N= 4/8 and if you simplifyit it will be N= 1/2

Hope this helped

Nady [450]
If I understood the question correctly the answer would be 6,630 crayons because there is 5 boxes of 1000 crayons or 5,000+ 6 boxes of 100 crayons or 600+ 3 boxes of 10 crayons or 30+ 1 box of 1000= 6,630. Hope this helps you. Sorry if I didn't fully understand what you wrote.
