For ex:
U have 4/8 - 6/2 u would probably have to use KCF- Keep Change Flip
So then it’ll be 4/8 + 2/6
U kept the 4/8 then u changed the subtraction to addition and u flipped the 2 to the numerator and the 6 denominator.
Idk my dude this is what I can think of
Here is the answer. First change 20cm in mm = 200mm
ratio = 70mm/200
= 7 : 20
Hope this helps! Mark brainly please!
k = -a + 4v/m
I hope this will help you.
