just find the ratio
30/18 to find the factor on which you need to multiply 24 to get the width of the new frame

xapproachesinfinity · Answer

actually you should 18/30 
because we are making a smaller frame

sorry i read the other way

xapproachesinfinity · Answer

you should get a fraction factor

xapproachesinfinity · Answer

3/5 is the ratio
so if we multiply 12 by that what should we get

xapproachesinfinity · Answer

lets actually make more simpler
$$\frac{30}{18}=\frac{24}{x} \Longrightarrow x=\frac{24}{30}\times 18$$

simplify and you get what you are looking for
