Flip should get 4 boxes.
6*5=30
30/8=3.75
round up for 4.
Note, since both factors have the same denominator, we can add the numerators together.
Numerator :
5n + (2m + 4n) = 5n + 2m + 4n = 9n + 2m
Denominator :
30m
Thus,
= (9n + 2m) / 30m
X - the divisor
288 : x = 12 ⇒ x = 288 : 12 ⇒ x = 24
Answer: the divisor is 24.
