Question

3,452 people visited a zoo on Saturday, and 2,877 people visited it on Sunday. Estimate how many more people visited on Saturday than on Sunday to the nearset tens.

• A. 570
• B. 500
• C. 470
• D. 600

Answer 1

The correct option is A 570

People visiting on Saturday = 3,452

People visiting on Sunday = 2,877

Estimating follows the given rules:

i. If the deciding digit < 5, then round down.

ii. If the deciding digit > 5, then round up.

iii. If the deciding digit = 5, then round up.

Difference = Number of people visiting on Saturday – Number of people visiting on Sunday

= 3,452 – 2,877

Rounding the numbers to the nearest tens, we get:

= 3,450 – 2,880

Subtracting the rounded numbers, we get:

So, 570 more people visited the zoo on Saturday than on Sunday.
