A collector has 180 movie posters and 120 band posters she always to sell 27 movie posters but still have the same ratio of 180:120 how many band posters does she sell

18 band posters

Step-by-step explanation: the ratio will always be 180:120 or 3/2

180-27 = 153 so if she sells 27 posters and the ratio is 3/2 then the amount of band posters left would be 153 divided by 3/2 = 153/1 * 2/3 = 102 so if there are 102 posters left and she had 180 then you would subtract them 120 - 102 = 18

repeat the question

step-by-step explanation:

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
