Question

estimate the product 824× 579 by rounding both the numbers to nearest 100​

Answer 1

Answer:

In 475 the last two digits i.e., 75 is greater than 50.

In 475 the last two digits i.e., 75 is greater than 50.Therefore, 1 will be added to the 3rd last digit and the last two digits will become zero.

In 475 the last two digits i.e., 75 is greater than 50.Therefore, 1 will be added to the 3rd last digit and the last two digits will become zero.After rounding to nearest hundred we will get 500.

In 475 the last two digits i.e., 75 is greater than 50.Therefore, 1 will be added to the 3rd last digit and the last two digits will become zero.After rounding to nearest hundred we will get 500.In 225 the last two digit i.e., 25 is less than 50

In 475 the last two digits i.e., 75 is greater than 50.Therefore, 1 will be added to the 3rd last digit and the last two digits will become zero.After rounding to nearest hundred we will get 500.In 225 the last two digit i.e., 25 is less than 50Thus, the 3rd last will remain same and the last digit will become zero.

In 475 the last two digits i.e., 75 is greater than 50.Therefore, 1 will be added to the 3rd last digit and the last two digits will become zero.After rounding to nearest hundred we will get 500.In 225 the last two digit i.e., 25 is less than 50Thus, the 3rd last will remain same and the last digit will become zero.After rounding to nearest ten we will get 200.

In 475 the last two digits i.e., 75 is greater than 50.Therefore, 1 will be added to the 3rd last digit and the last two digits will become zero.After rounding to nearest hundred we will get 500.In 225 the last two digit i.e., 25 is less than 50Thus, the 3rd last will remain same and the last digit will become zero.After rounding to nearest ten we will get 200.Hence, the required product is 500×200=1,00,000

Answer 2

Answer:

824 will be 800

579 will be 600

so 800×600=480 000
