Using no other digits except 2 and 5 write down, if possible, a three-digit multiple of 3 but not of 6

225

Step-by-step explanation:

225/3 = 75

225/6 = 37.5 (since this is not a whole number it's not a multiple of 6)

Final answer = 225

Hope this helps!

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
