Lesson 16 Reason About Quotients

Warm-up Estimation Exploration: How Many One Fifths?

$98 \div \frac{1}{5}$

Record an estimate that is:

too low	about right	too high

$25 \div \frac{1}{5}$

$\frac{1}{7} \div 25$

$\frac{1}{8} \div 25$

$25 \div \frac{1}{7}$

$25 \div \frac{1}{8}$

$\frac{1}{5} \div 25$

Without finding the value of the expressions, write each expression under the correct category.
The value of the expression is less than 1
The value of the expression is greater than 1
Explain your strategy for determining whether a quotient is less than 1 or greater than 1.

Find the value of each expression. Explain or show your reasoning.

The value of the expression is less than 1	The value of the expression is greater than 1
