Which of the following is not true in a dialation?

ANSWER:

( 2 ) The image and preimage are different shapes.

EXPLANATION:

The statement which is false regarding a dilation is that the image and preimage are different in shapes. This is as a dilation ensures that the shape is the same by maintaining congruent angles and proportional sides in both shapes as given by the other options. Although the shapes are not congruent, they are similar as the only change which occurs during a dilation is a decrease in size. No changes are made to its shape.

2/3 = 8/12 and 3/4 = 9/12

Step-by-step explanation: You need to find the LCD (Least Common Denominator) by listing the factors. For example: 1/3 and 4/5

3: 3, 6, 9, 12, 15 ect.

5: 5, 10, 15, 20, 25 ect.

The lowest number they both have in common is 15.

Do that with the 3 and 4 from 2/3 and 3/4

3: 3, 6, 9, 12

4: 4, 8, 12, 16

The LCD there is 12.

Now you have 2/12 and 3/12

You need to multiply the top number (2 in 2/12) by 4 (which is 8), since thats what we did to get 12 on the bottom number.

Next do that with the other fraction.

Now you have 8/12 and 9/12!

Sorry if it is a little unclear, its kinda hard to explain.
