Intro

- Hi, welcome to this question right here. So, we're trying to redraw this shape right here, using a scale factor of one-quarter. So, it's gonna get smaller. But, how much smaller? About a quarter smaller, right? 
So, what we're gonna do is, we're gonna figure out the, I guess, how many units you have on the original part first, right? So, if I count it on the middle line right there, that's about 8 boxes in total. And the high here is just gonna be 2 boxes here, and 2 boxes here. And from here to here, it's just going to be 1, 2, 3, 4, looks like a 5, okay? 
Now, we're gonna take this whole...every dimension here and we're gonna divide by 4. So, let's look at the center line first, because it's easier. 8 divided by 4, what do we have? We've got 2. So it's gonna be very small. So I come over to the center line right here. I'm gonna draw a center line and that's gonna be a new shape right there. If I divide this 8 by 4, right? So, I've got 2 right now. Now, it's gonna go from the center down to this one before. Remember, you're multiplying by a quarter, which means you're dividing by four. So, what's 2 divided by 4? It's gonna be a one-half and one-half is 0.5. So from the center line I'm gonna go down 0.5 so, about here I'm gonna stop. Go up 0.5 and I'm going to stop. Because I've got to figure out how much is, how long is here and how long is here. Well, this is 5. From the center of the figure here, this is 5 so, if I take this 5 here and divide by 4, I've got 1.25. And it's like this, a 1.25 is the total length. From here to here is 1.25 so, it's a little bit approximate. It doesn't have to be very exact. So, here's my 1.25. Here's my little 1.25 right there. Let me redraw it a little bit. So, 1.25. So at the end we're just gonna put everything together. And there you go. That is your new drawing. If you times it by a one-quarter? Kind of look small but, there's nothing else we can do. Divide everything by 4, that's what you get. Thanks for watching.

Reducing a shape using a scale factor of one quarter

Redrawing the letter H using a scale factor of 2

Enlarging the letter E using a scale factor of 2

Understanding scale factors for enlargements and reductions

When you are asked to make an object bigger or smaller, you will ask, "by how much?" In this case, scale factor can help answer the question. In this lesson, we will practice how to enlarge and reduce objects according to the scale factors given to us.

What is a scale factor?

Mastering Enlargement and Reduction Scale Factors

What You'll Learn

Identify scale factors and determine whether they create enlargements or reductions

Apply scale factors to multiply dimensions of shapes and objects

Calculate missing dimensions using ratios and scale factors

Recognize that scale factors greater than 1 create enlargements and less than 1 create reductions

What You'll Practice

Redrawing letters and shapes with whole number scale factors

Creating scaled figures with fractional scale factors (1/4, 0.5)

Calculating new dimensions of windows and objects using given scale factors

Determining scale factors from pairs of similar shapes using side ratios
