b) 240000
c) 2400000
d) 3000000​

Answer 1

Answer:

c) 2400000

Step-by-step explanation:

5980 × 428

6000 × 400

2400000

Answer 2

2400000 is the estimation of the  product 5980×428 by rounding off each number to the nearest hundreds

Given:

5980×428

To Find:

Estimate the product by rounding off each number to the nearest hundreds.​

Solution:

Procedure to rounding off to nearest hundred

Check the digit at tens place

If digit at tens place is less than 5 than then make Tens and unit Digit 0 and all other digits remains same

If digit at tens place is 5 or more  than 5 then make Tens and unit Digit 0 and add 1 in hundreds digit

Step 1:

Rounding off 5980

Digit at tens place is 8   hence increase the digit at hundred place by 1

9 + 1 = 10  Hence 1s carried over to 5 => 5 + 1 = 6

Hence 5980 rounded off to 6000

Step 2:

Rounding off  428

Digit at tens place is 2   hence no change in the digit at hundred place

Hence 428 rounded off to 400

Step 3:

Find the product of 6000 and 400

6000 x 400  = 2400000

Estimation of the  product 5980×428 by rounding off each number to the nearest hundreds.​ is 2400000

Correct option is c) 2400000
