Proportional Reasoning, Quarter 1 Review

Hello! This is a new type of Quizizz we are going to try out. You have plenty of time per question.

First, we will focus on ratios! Let's get started!

Multiple Choice

Ella has 5 balloons and Tyler has 7 balloons. What is the ratio of the number of balloons Ella has to number of balloons Tyler has?

• 7:5

• 5:13

• 13:7

• 5:7

Multiple Choice

What is the ratio of orange circles to blue circles?

• 2:3

• 3:5

• 3:2

• 2:5

Multiple Choice

What are the three ways to write a ratio that shows 2 of something to 3 of something? 

• 2-3,  2:3,   $$\frac{2}{3}$$

• 2 to 3,  2:3,   $$\frac{2}{3}$$

• 3 to 2,  2:3,   $$\frac{2}{3}$$

Multiple Choice

What is a ratio?

• A number over another number

• Multiplying two fractions

• Two decimals that are multiplied

• A comparison of two numbers

Multiple Choice

There are 4 birds and 6 snakes. What is the ratio of birds to snakes?

(Remember to simplify when writing ratios as fractions. :)

• 6/4

• 2/3

• 1/3

• 10/16

Alright! Now we are going to get into similar v. congruent figures. Are you ready? Let's do this!

• Congruent

• Neither

• Similar

Multiple Choice

Line AB corresponds with what line.

• XZ

• XY

• YZ

• YX

Remember these rules:

*SIMILAR FIGURES: Must be the same shape, have congruent corresponding angles, & be in proportion

*CONGRUENT FIGURES: Are exact copies, same shape, same angles, same sizes

Multiple Choice

Are the following figures similar? Why or why not?

(Click the image to make it larger.)

• Yes. All pairs of corresponding angles are congruent (or the same).

• No, the corresponding angles are not equal.

Multiple Choice

Tell whether the two figures are similar. Explain your reasoning.

• Yes, similar because they are the same shape and side lengths are proportional.
• No, not similar because they are the same shape, but side lengths are not proportional.
• Yes, same shape
• No, different sizes

Multiple Choice

Are the following similar? Why or why not?

• Yes, just because.

• No, the corresponding angles are not equal.

• No, the ratios of the corresponding sides are not equal.

Multiple Select

Click the THREE things two figures must have in order to be similar:

• Must be the exact same size

• Must be the same shape

• The shapes must be proportional to each other

• Must have the same angle measurements (congruent corresponding angles)

This is our last stop! Let's practice scale factor!

Multiple Choice

Going from left to right, what is the scale factor?

(Click on the image to make it larger.)

• multiplied by 1.5

• divided by 1.5

• multiplied by 2.5

• division by 2.5

Multiple Choice

If the scale factor is less than one, the new figure will be

• an enlargement

• a reduction

• a scale factor

• bigger

Multiple Choice

If a Scale Factor if greater than 1, then your figure gets...

• Smaller

• Bigger

• Does not change

Multiple Choice

Looking from left to right, what is the scale factor?

• 4

• .25

• 5

• 6

Multiple Choice

If the scale factor is 4, what is the measurement of x?

• 20 m

• 24 m

• 16 m

• 4 m

This rectangle has a width of 2cm and a length of 5cm.

What would be the new dimensions if we took that rectangle to a scale factor of 5?

Open Ended

This rectangle has a width of 2cm and a length of 5cm.

What would be the new dimensions if we took that rectangle to a scale factor of 1/2?

Great work! Keep playing until you earn a 100%! You can do it!
