Emma
and Jammie used base ten block to show that 40 is 1/10 of 400
=> so Let say Emma and Jammie have 400 pieces cubes and they have base ten
block. To know how many base ten block are there in 400, they need to separate
the 400 pieces cube into ten per group.
=> 400 divided by 10
=> 400 / 10 (how many base ten blocks
are there in 400)
=> 40, thus, there are 40 base ten blocks in 400 pieces of cubes.
Therefore 40 is the 1/10 of 400.
