Calculate 60% of 140: Finding the Number of Adults in a Group

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

• Step 1: Identify the total number of people, which is 140.
• Step 2: Recognize that 60% of these are adults.
• Step 3: Convert 60% into a decimal fraction: $\frac{60}{100} = 0.6$.
• Step 4: Multiply the total number of people by the decimal fraction: $0.6 \times 140$.

Now, let's perform the calculation:
Step 1: We have 140 people in total.
Step 2: 60% of these are adults.
Step 3: Converting 60% to a decimal gives us 0.6.
Step 4: Multiply 0.6 by 140:

$0.6 \times 140 = 84$

Therefore, the number of adults in the group is 84.
