Presentation On Monday, we learned how to add and subtract fractions by finding common denominators and making equivalent fractions. Today, you will learn how to solve problems using multiplication and division of fractions.

We can add and subtract fractions with the same (common) denominator easily. Review: Adding and Subtracting Fractions =

When multiplying and dividing fractions, we do not need to have common denominators. Multiplying and Dividing Fractions 3535 x 1313 = These do not have to be the same!

To multiply fractions, simply multiply the two numerators and the two denominators. Multiplying Fractions 3535 x 1313 = x = ????

To multiply fractions, simply multiply the two numerators and the two denominators x 1313 = x = 3?3? Multiplying Fractions

To multiply fractions, simply multiply the two numerators and the two denominators x 1313 = x= 3?3? Multiplying Fractions

To multiply fractions, simply multiply the two numerators and the two denominators x 1313 = x= 3 15 Multiplying Fractions

If possible, state in simplest form. Multiplying Fractions 3535 x 1313 = 3 15 = 1515

To divide by a fraction, you must multiply by its reciprocal. To find its reciprocal, simply flip the fraction over! Dividing Fractions The reciprocal of 3/5 is 5/3.

Example: 3535 ÷ 1313 Dividing Fractions = 3535 x 3131 = Multiply by the reciprocal… 9595

Learning Together Our goal: I can multiply fractions and use the “Keep, Change, Flip” method to divide fractions. Assignment: Multiplying & Dividing Fractions practice sheet with your partner(s). *You have 30 minutes to complete the 11 problems*

Just For Me Complete the Pizzazz puzzle titled “Moving Words” by yourself.

Ticket out the Door (Assessment) Find the area of a rectangle with a length of and a width of. Don’t forget to put your name on your notecard

Wrap Up Homework: Complete the Pizzazz puzzle (if you did not finish). This is due on Friday at the beginning of class. Take your journal home to help you. If you finished, put your journal back in the bin. How did we do today? Did we maintain classroom operating procedures? Did we work toward our learning goals? We will learn how to solve problems using multiplication and division of fractions. Did we complete the tasks?
