Can someone help me with part b of question please.

1.75:1

Step-by-step explanation:

1. A ratio is like a fraction, so 7:4 = 7/4. When they're asking you to put it into n:1 form, they're asking you to make the denominator one.

2. What they're asking:

              7/4 = n/1

3. Solve for x:

      n =1.75

4. Put it into ratio form:

          1:75:1

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
