Answer:
3
Step-by-step explanation:
Numbers between 21 and 30 divisible by 3 are 24 and 27. so you get the HCF of the two.
As an expression, this is:
222c - 15 = c
If you want to solve it, add 15 to each side to get:
222c = c + 15
Subtract c from each side:
221c = 15
Divide each side by 221:
c ≈ 0.0678733
