The Blinking Rockets baseball team has had 127,034 visitors to their fan website. Rounded to the nearest ten thousand how many v
horsena [70]

Answer:

Visitors = 130000

Step-by-step explanation:

Given

Visitors = 127034

Required

Approximate to the nearest ten thousand

First, identify the digit at the ten thousand position

From the given numbers of visitors, the digit is 2.

So, the next digit (which is 7) will be approximated and added to 2.

7 > 5. So, 1 will be added to 2.

The number of visitors becomes:

Visitors = 130000
