Question

Can someone please help me solve this

Answer 1

Answer:

see explanation

Step-by-step explanation:

The scale factor is the ratio of corresponding sides, image to original , then

P → Q = $\frac{5}{4}$ = 1.25

Q → P = $\frac{4}{5}$ = 0.8

Answer 2

Answer:

1. 1.25

2. 0.8

Step-by-step explanation:

1. 2 : 2.5 = 1.25 Ratio from P To Q - 1 : 1.25

2. 2.5 : 2 = 0.8 Ratio from Q to P - 1 : 0.8

1. All you have to do is find the corresponding sides(meaning similar) and the compare them from one to another.

Example:

I know 5 and 4 are corresponding sides because they are similar. The ratio is Q to P we can find by writing them down. It can be written like this.

5:4 is so when we multiply this ratio from any side of Q we will get the correpoding side from P.

5:4 ratio = 1 : 0.8 - So the ratio is 0.8

There this is another ratio that we can compare to.

Now let’s say we need to find when the one of the P side is 4 and what would be the corresponding side.

4 x 1.25(ratio from P to Q) = 5

We can also find when the P side is 3 what would be Q’s corresponding side. Which is the ratio from P to Q or 1.25.

So just multiply 3 by 1.25.

3 x 1.25 = 3.75

3.75 x 0.8 = 3
