Need help with my work pleasem

Answer 1

Let me start with the second screenshot :-
To find the scale factor you have to enlarge/ dilate A to get B you have a given side so assume that all sides are dilated to the same extent
: .
`1 (1)/(2) / (3)/(4) = 2`

Thus one can say m would be

`(1)/(2) * 2 = 1`

And N would be

`(5)/(6) * 2 = (10)/(6)`
