Answer 2

Answer:

27,000

Step-by-step explanation:

Given :- The given numbers are 87 and 313.

To Find:- Rounded estimate of 87 × 313.

Solution:-

The given product is 87 × 313 .

Here we are asked to find the rounded estimate value for the above given product.

So, we will round off the given numbers to nearest 10's or 100's as required.

The number 87 will be rounded off to 90 as the digit at the unit's place is 7 which is greater than 5. So we replace 7 by 0 and add +1 to the digit at ten's place.

The number 313 will be rounded off to 300 as the digits at unit's place is 3 which is less than 5 and the digit at ten's place is 1 which is also less than 5. So we replace 1 and 3 by 0 and write the digit at hundred's place as it is.

So, the estimated value of the product = 87 × 313

                                                                 = 90 × 300

                                                                 = 27000

Therefore the rounded estimate of 87 × 313 is 27,000 .
