Answers
Given : a man wants to buy a piece of wood that is 484 units long.
wood is sold only in length of 100 units.
To Find: Approx how much wood should he buy
Solution:
man wants to buy a piece of wood = 484 units
wood is available in 100 units only
Hence round up 484 upto hundreds place
Hundred place = 4
Tens Place = 8
Ones place = 4
if Tens Place ≥ 5 then hundred place will be increased by 1
if Tens place < 5 then hundred place will remain same
and all digit after hundred place will become 0
Tens Place = 8 > 5
Hence hundred place = 4 + 1 = 5
Hence 484 is approx 500
Approx 500 units he should buy.
