Summative Assessment: Multiplying and Dividing with Fractions

Fill in each blank with the appropriate symbol:

$$5\left(\frac{3}{4}\right)$$ ​ (a)   $$5$$

$$5\left(\frac{5}{4}\right)$$ ​ (b)   $$5$$

$$5\left(\frac{3}{3}\right)$$ ​ (c)   $$5$$

Describe a situation or problem to explain why multiplying by 2/3 will make a value smaller.

Fill in each blank with the appropriate symbol:

$$5\div\frac{3}{4}$$ ​ ​ (a)   $$5$$

$$5\div\frac{5}{4}$$ ​ (b)   $$5$$

$$5\div\frac{3}{3}$$ ​ (c)   $$5$$

Draw a picture to show why dividing a value by 1/2 makes a number greater than the original value.

Draw a model to represent the multiplication statement $$\frac{2}{5}\cdot\frac{2}{3}$$

The model matches which multiplication problem below?

What expression is modeled above?

Multiply and simplify: $$\frac{3}{4}\cdot\frac{8}{5}=$$  

Jose is selling clay pots to raise money for a hunger outreach program in his hometown of Bogota. Each pot requires $$1\frac{1}{2}$$ packages of clay. He plans to make 10 pots. How many packages does he need?
