c) 155
d) 165

Answer 1

A child who is 12 years and 5 months old is 149 months old, calculated by multiplying the years by 12 and then adding the remaining months.

Step-by-step explanation:

The age in months of a child who is exactly 12 years and 5 months old can be calculated by converting the years into months and then adding the additional months. There are 12 months in one year, so:

• 12 years × 12 months/year = 144 months
• Adding the extra 5 months: 144 months + 5 months = 149 months

Therefore, the correct answer is that a child who is 12 years and 5 months old is 149 months old.
