Question

The list shows the number of visitors to an exhibition. 185 349 107 355 451 Estimate, by rounding each number to the nearest 100, how many visitors there were.​

Answer 1

To estimate the number of visitors by rounding each number to the nearest 100, round down if the ones place is less than 50 and round up if it's 50 or greater. Then add up the rounded numbers to get the estimate.

Step-by-step explanation:

To estimate the number of visitors by rounding each number to the nearest 100, you need to look at the ones place of each number. If the ones place is less than 50, round down to the nearest hundred. If the ones place is 50 or greater, round up to the nearest hundred.

Let's go through the numbers:

• 185 rounds down to 100
• 349 rounds up to 400
• 107 rounds down to 100
• 355 rounds up to 400
• 451 rounds up to 500

Now add up the rounded numbers: 100 + 400 + 100 + 400 + 500 = 1,500

Answer 2

Answer: Total visitors =1500

Step-by-step explanation:

By rounding off each no. nearest to 100 is :

185=200, 349=300, 107=100, 355= 400. 451= 500

By adding round off no. i.e.200+300+100+400+500= 1500

So total no. of visitors were 1500
