(A) To find the number of times the digit $5$ appears in numbers from $1$ to $100$,we count the occurrences in two positions: the units place and the tens place.$1$. In the units place: The digit $5$ appears in $5, 15, 25, 35, 45, 55, 65, 75, 85, 95$. There are $10$ such numbers.$2$. In the tens place: The digit $5$ appears in $50, 51, 52, 53, 54, 55, 56, 57, 58, 59$. There are $10$ such numbers.Note that the number $55$ is counted in both lists because it has a $5$ in both the units and tens places.Total count = (Count in units place) + (Count in tens place) = $10 + 10 = 20$.Therefore,the digit $5$ appears $20$ times.

How many times does the digit $5$ appear when writing natural numbers from $1$ to $100$?
