How it works
• When Pakistani government carries census, it tries to count, very accurately, every person living in the country.
• For example…• If some one asks Sid his age, Sid does not answer 15 years ,4
months ,12 days ,15 hours,3 minutes and 33 seconds! He simply says:
• I AM 15 !• Sid has ROUNDED OFF his age to the nearest year• And, if you ask • Sid how many people live on super globe, he certainly won’t
remember that the number is 87,688,000. But he • might be able to say about 88,000,000. • Sid has ROUNDED OFF the number to the nearest million

HOW TO ROUND OFF
• Rounding off is a useful short cut. its helps us give approximate answer when exact answer are not needed.
• To round off the number to the nearest 10,look at the numbers in the ones place. we round down if that number is smaller than 5 and round up if it is 5 or bigger than 5.
