How do you find the percent change from 84 to 63?

25% Change

Step-by-step explanation: To find the percent change from 84 to 63, we will be using the "percent change" equation.

change = percent change x actual

To find the change subtract 63 from 84. 84 - 63 = 21. So the change is 21.

21 = percent change x actual

The actual is 84, because 84 is your original amount.

21 = percent change x 84  (Solve for p, percent change.)

21 = p x 84

21/84 = p

0.25 = p

Now, multiply the decimal 0.25 by 100 to get the percent change.

0.25 x 100 = 25, Or a 25% change.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
