Final answer:
The pairs of numbers that have 12 as their greatest common factor are d) 36 and 60, and e) 48 and 72.
Explanation:
The subject of this question is finding numbers that have the greatest common factor (GCF) of 12. In mathematics, the GCF of two numbers is the largest positive integer that divides exactly into the two numbers without leaving a remainder. Let's consider each pair of numbers to select all the correct answers.
- For pair a) 3 and 4, the GCF is 1, not 12.
- For pair b) 6 and 12, the GCF is 6, not 12.
- For pair c) 24 and 48, the GCF is 24, not 12.
- For pair d) 36 and 60, the GCF is indeed 12.
- For pair e) 48 and 72, the GCF is also 12.
- For pair f) 84 and 96, the GCF is 12, not 12.
So, the pairs of numbers that have 12 as their greatest common factor are the pairs: d) 36 and 60, and e) 48 and 72.
