Question

Estimate 749 × 624 by rounding off each number to the nearest hundred

Answer 1

Answer:

4200

Step-by-step explanation:

Let the 2 numbers be 'x' and 'y' respectively with the answer as 'k'

x=749

y=624

k=rounded off x*rounded off y

Round off x=749 to 700[this is because 4 in the tenth place is less than 5 and so 749 will get converted to 700]

Round off y=624 to 600[this is because 2 in the tenth place is less than 5 and so 624 will also get converted to 600]

k=rounded off x*rounded off y

 =700*600

k=4200
