Answer:100×40=4000

Step-by-step explanation:

we see the last digit we round off it

If the digit is less than 5 so it will be remain same and If it's bigger than 5 so we ADD one number in it

THUS,WE WILL ROUND OFF 99 TO 100 AS THE LAST DIGIT IS BIGGER THAN 5 SO WE WILL ADD 1

AND WE WILL ROUND OFF 39 TO 40 AS THE LAST DIGIT IS BIGGER THAN 5 SO WE WILL ADD 1
