To answer this question, we need to determine how many times we can subtract 6 from 30.
Every time we subtract 6 from 30, we will have 24 left. We can continue subtracting 6 from this result until we reach 0.
Let's go through each option to understand why it is correct or incorrect:
Option A) 5 - This option is incorrect because we can subtract 6 from 30 more than just 5 times.
Option B) 3 - This option is incorrect because we can subtract 6 from 30 more than just 3 times.
Option C) 0 - This option is incorrect because we can subtract 6 from 30 at least once.
Option D) 1 - This option is correct because we can subtract 6 from 30 once, resulting in 24.
The correct answer is D. This option is correct because we can subtract 6 from 30 once, resulting in 24.
