The fabric Hannah needs costs $4.65 per yard.
She has $23.50. About how many yards of
fabric can she buy?

To find about how many yards Hannah
can buy, estimate: $23.50$4.65.

Use compatible numbers to estimate the quotient
of two decimals (or two money amounts):

Write the nearest compatible whole $23.50 $24
numbers for the dividend and the divisor. 0 $4.65 0 $4

Divide. $24$4 6

She can buy about 6 yards of fabric.

Compare the dividend and the divisor to help
estimate a quotient if it is greater than or less than 1.
