Kwan has modeled a number that is less than 999. His model has twice as many 100-blocks as 10-blocks. It has twice as many 10-blocks as 1-blocks. What is the number?
842
It could be 421 or 842.

If the number of boys in ninth grade is 12 less than twice the number of girls there are 51 astudents in ninth grade then the number of girls is 21

There are fifteen (15) nickels.
n=unknown 1-block n+2(n)+2(2n) n+2n+4n Thats the answer because a number was never given. If you want to assume theres an invisible 1 infront of n then heres the problem for that 1n+2(1n)+2(2n) 1n+2n+4n so answer would be 421 BUT you can make it complicated if read the question again. Although they never gave a number, the question wrote 1-blocks as a plural (notice the s at the end of blocks). So assuming there is more than one 1-block we can say there are two 1-blocks. Lets solve this one n=2 (since theres more than 1 ones blocks) n+2(n)+2(2n) 2+2(2)+2(4) 2+4+8 so the answer would be 842 These two answers are possible and they are both under 999.

Since there are infinitely many numbers you will need infinitely many blocks.
The number of city blocks in 1200 acres would depend on the size of the blocks. The number would vary based on the dimensions of each block.
Over twice, but less than about 7.
If a "certain number of men" less 10 takes 20 days (twice as long) to finish the piece of work, then the "certain number of men" who can finish the work in 10 days would 20. If it takes 10 men less twice as long to do the work, then twice 10 men (20) can finish the job in 10 days.
