Answer:
1300000
Step-by-step explanation:
number to be rounded off to the nearest lakh
: 1263792.
when we are rounding off to the nearest lakh, we will look at the number in the ten thousand (10000) position. if the number is greater than or equal to 5. then the number in the lakh position will increase by 1. All the other number places will turn to 0.
If the number in the ten thousand position is less than 5 , the number in the lakh remains changed and the rest of the number positions will turn to 0.
in this case the number in the ten thousand position is 6 . 6 is greater than 5, therefore the number in the lakh position 2 will be increase by 1 and become 3.
Thus 1300000.
