Answer 2

Answer:

i) $8074 + 4178=12300$

ii) $1768977 + 130589=1899600$

Step-by-step explanation:

To find : Estimate by rounding off each number to the nearest hundred ?

Solution :

Rounding off to nearest hundred,

1) If the tenth digit is greater than or equal to 5 then hundred place is added up by 1 and rest became zero.

2) If the tenth digit is less than 5 then hundred place remain same and rest became zero.

(i) $8074 + 4178$

Rounding 8074 to nearest hundred = 8100

Rounding 4178 to nearest hundred = 4200

$8074 + 4178=8100+4200$

$8074 + 4178=12300$

(ii) $1768977 + 130589$

Rounding 1768977 to nearest hundred =1769000

Rounding 130589 to nearest hundred = 130600

$1768977 + 130589=1769000+130600$

$1768977 + 130589=1899600$
