Help pls!! Which scale factor was used to transform triangle MNP to triangle RST?

Step by step explanation:

Here two triangles are given to us . The two triangles are ∆MNP and ∆RST. They are similar to each other . That is ,

Now we know that the corresponding sides of the similar triangles are proportional . Hence here ,

Here we are given the value of side NP as 7 and ST as 2 . So here we can find out the scale factor by dividing these two .
