Respuesta :

Option C

Answer:

If height of Archie is m millimeter in picture, then actual height in inches is ([tex]\frac{1}{2}[/tex])m inches. Hence correct option is C

Solution:

Given information is  

Archie has a picture of himself and five friends.

Height of one friend in image in millimeter = 130.

Actual height of that friend in inches is = 65

It means 130 millimeter of picture = 65 inches of actual  

So 1 millimeter of picture = ([tex]\frac{65}{130}[/tex]) inches in actual.

So m [tex]\times[/tex] 1 millimeter in picture =  ([tex]\frac{65}{130}[/tex]) [tex]\times[/tex] m inches in actual.

So if height of Archie is m millimeter in picture, than actual height in inches is ([tex]\frac{65}{130}[/tex])m = ([tex]\frac{1}{2}[/tex])m inches .

Hence correct option is C
