Answer 1

The number of adults going on a field trip was 47, as it is the largest prime number less than 50 among the given options.

Step-by-step explanation:

The number of adults going on a field trip was the largest prime number less than 50. To find this, we need to check the given options and identify the largest prime number among them. Prime numbers are numbers that have only two distinct positive divisors: 1 and the number itself.

• 41 is a prime number.
• 43 is also a prime number.
• 47 is a prime number as well.
• 49 is not a prime number because it can be divided by 7 (7x7=49).

Among these options, 47 is the largest prime number. Therefore, the number of adults going on the field trip was 47.
