When using base-10 blocks to divide 452 by 2, how many hundreds flats will be in each equal group? hundreds flats divide 452 by 2 using base-10 blocks - 4 hundreds flats, 5 tens rods, and 2 ones cubes placed side-by-side

Given

4 hundreds flats; 5 tens rods; 2 ones cubes

Find

The number of hundreds flats in each of 2 equal piles

Solution

When 4 flats are divided into two equal groups, each group will have ...

... 2 flats

You can imagine doing this the way a card dealer might: first put 1 flat in each of 2 piles, then do the same for the remaining 2 flats. Each pile will end up with 2 flats.

You will have a problem if you continue with the tens rods. There is an odd number of those, so one of them will have to be exchanged for 10 ones cubes.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
