Answer:

124,000 can be the actual number

Explanation:

* Lets explain how to solve the number

- The number of visitors to the park is 120,000 visitors rounded

to the nearest ten thousands

- The round to nearest digit means look to the digit before this

digit if < 5 we put all the digits before the rounded digit zero and

keep it as it, if the number before the rounded digit is ≥ 5 we put

all the digits before the rounded digit zero and add the rounded

digit by 1

- Ex:

# To round 12,345 to the nearest thousand look to the hundred

digit (3), 3 < 5 , then the rounded number is 12,000

# To round 12,745 to the nearest thousand look to the hundred

digit (7), 7 > 5 , then the rounded number is 13,000

- To find the actual number lets do these steps

1. Divide the ten thousands by 2

10,000 ÷ 2 = 5,000

2. Add the result and subtract the result from the rounded number

∵ 120,000 - 5000 = 115,000

∵ 120,000 + 5000 = 125,500

3. The actual number is between these two numbers

115,000 ≤ actual number < 125,000

- Remember: we can not take the number 125,000 as the actual

number because when we round it to the nearest ten thousand

the answer will be 130,000

∴ You can chose any numbers belongs to this range

* I will chose 124,000 can be the actual number
