There are exactly 45 two-digit numbers that are divisible by 2.
Here's a step-by-step explanation based on the provided reference:
- Total Two-Digit Numbers: There are 90 two-digit numbers in total (from 10 to 99).
- Divisibility by 2: Every other number is divisible by 2 (i.e., even).
- Calculation: Since there are an even number of total two-digit numbers, precisely half of them are divisible by 2. Thus, 90 / 2 = 45.
Therefore, 45 two-digit numbers are divisible by 2. This conclusion aligns perfectly with the information derived from the reference, which stated, "number of two digit numbers divisible by 2 = total/2 = 90/2 =45."
