Consecutive Numbers up to 100 - Examples, Exercises and Solutions

Let's solve this step-by-step:

• Step 1: Identify the given number, which is 6700.
• Step 2: Use the formula for finding the predecessor of a number, which is to subtract 1 from it. Thus, $6700 - 1 = 6699$.
• Step 3: Verify the calculation by adding 1 back to the result: $6699 + 1 = 6700$, confirming our result is correct.

After following these steps, we conclude that the predecessor of the number 6700 is $6699$.

To determine the number that comes immediately before 31,000, we need to find its predecessor.

Step 1: We start with the number 31,000.

Step 2: To find the predecessor, we subtract 1 from this number:

$31,000 - 1$

$= 30,999$

This calculation tells us that the number that comes before 31,000 is 30,999.

Therefore, the correct solution to the problem is $30,999$.

To determine which number follows 54,549, follow these steps:

• Step 1: Identify the given number, which is 54,549.

• Step 2: To find the next number, simply add 1 to the given number.

Let's calculate:

$54,549 + 1 = 54,550$

Therefore, the number that follows 54,549 is $54,550$.

To find the number that comes before $31,440$, we need to calculate the predecessor using subtraction. Let's go through the steps:

• Step 1: Identify the given information. We have the number $31,440$.
• Step 2: Determine the predecessor by subtracting 1 from the given number. Use the formula: $\text{Predecessor} = n - 1$.
• Step 3: Perform the calculation: $31,440 - 1 = 31,439$.

Thus, $31,439$ is the number that comes before $31,440$.

Therefore, the correct answer is $31,439$.

To solve the problem of finding the number that follows 70,099, we will apply the steps below:

• Step 1: Identify the given number. In this case, it is 70,099.
• Step 2: Apply the formula for finding the successor, which is to add 1 to the given number. Hence, $70,099 + 1$.
• Step 3: Perform the calculation: $70,099 + 1 = 70,100$.

Thus, the number following 70,099 is $70,100$.
