Number Comparison: Identifying Values Less Than 87

Which group contains numbers that are smaller in value than 87?

To solve this problem, we'll follow these steps:

• Step 1: Review the groups of numbers provided in the answer choices.

• Step 2: Compare each number in the groups with the value of 87.

• Step 3: Identify which group contains only numbers that are all less than 87.

Let's carry out these steps:

Step 1: Review the possible answer choices:
Choice 1: $10, 2, 60, 77, 40$
Choice 2: $87, 45, 30, 73, 71$
Choice 3: $75, 99, 80, 84$
Choice 4: $81, 90, 61, 74$

Step 2: Compare each number in each choice to the number 87:

Choice 1:
- $10 < 87$
- $2 < 87$
- $60 < 87$
- $77 < 87$
- $40 < 87$

Choice 1 satisfies the condition as all numbers are less than 87.

Choice 2:
- $87$ is not less than 87.

Choice 3:
- $99$ is not less than 87.

Choice 4:
- $90$ is not less than 87.

Thus, only Choice 1 contains numbers that are all less than 87.

Therefore, the solution to the problem is $10, 2, 60, 77, 40$.
