Chompy ate 24 apples from a bag that had 32 total apples. Write the fraction of apples Chompy ate in simplest form.

• $\frac{6}{8}$

• $\frac{20}{28}$

• $\frac{3}{4}$

• $\frac{30}{40}$

Bowser Jr. takes $\frac{6}{8}$  of an hour to get ready for bed. Chompy takes $\frac{1}{3}$  of an hour to get ready. Does Bowser Jr. take more time or less time than Chompy?

*Hint* - Use your fraction wall to compare the fractions, or change the denominator of both fractions to a common multiple.

• They take they same amount of time. 

• Bowser Jr. takes less time than Chompy.

• You cannot compare the fractions. 

• Bowser Jr. takes more time than Chompy.

• $\frac{4}{10}$ Yes, the fraction can be simplified.

• $\frac{4}{10}$ No, the fraction cannot be simplified.

• $\frac{6}{10}$ Yes, the fraction can be simplified.

Which fraction is in simplest form?

• $\frac{4}{8}$

• $\frac{12}{48}$

• $\frac{1}{13}$

• $\frac{10}{100}$

What are the tricks to know if a fraction is in simplest form? (There is more than 1 answer).

• The numerator is a 1.

• Use the force to identify the fractions in simplest form.

• Both the numerator and denominator are prime numbers.

• If the numerator is prime, and is not a factor of the denominator.

• If the numerator is EXACTLY one less than the denominator.

When we multiply by a fraction that has the same numerator and denominator (such as  $\frac{2}{2}$  ) we are actually multiplying by which number?

• 1: I know this because fractions are actually division problems, and any number divided by itself is 1, and any number multiplied by 1 has the same value.

• 0

• The number used for the numerator and denominator.

• 1,480,876

When we simply fractions, are we dividing fractions?

• YES! This is exactly how we divide fractions!

• Yes, dividing fractions is easy peasy lemon squeezy.

• NOOOO!!! Mrs. Down told me that we would be learning how to divide fractions in a few weeks!

  When we simplify fractions, we are just giving the fractions a makeover, and we are using the division operation to help us do that.

• Yes.
