Mei bought 6 containers of apple juice
for $1.90. To the nearest cent, what
is the cost of each container of juice?
To find the cost of each container, n,
divide: $1.90 6 n.
First estimate by using compatible numbers:
$1.80 6 $.30. Then divide.
Sometimes the division results in a remainder,
no matter how many zeros are written in the
dividend. You can round these quotients. In this
case, the quotient is rounded to the nearest
cent (hundredths place).
$ .31 6 Divide to the thousandths $.3 16
