Haryana Board 6th Class Maths Solutions Chapter 1 Knowing Our Numbers Exercise 1.3<\/h2>\n

Question 1.
\nEstimate :
\n(a) 730 + 998
\n(b) 796-314
\n(c) 12,904 + 2,888
\n(d) 28,292 – 21,496.
\nSolution:
\n(a) We find 998 > 730.
\nRound off to hundreds
\n\"HBSE
\nActual answer = 730 + 998 = 1728
\n1728 is rounded to 1700.<\/p>\n

\"HBSE<\/p>\n

(b) To begin with, we round off to hundreds
\n\"HBSE
\nActual answer = 796 – 314 = 482
\n482 is rounded to 500.<\/p>\n

(c) We find 12,904 > 2,888
\nRound off to thousands
\n12,904 is rounded to 13,000
\n+2,888 is rounded to 3,000
\n\u2234 Estimated sum = 16,000
\nActual answer = 12,904 + 2,888 = 15,792<\/p>\n

(d) To begin with, we round off to thousands
\n28,292 is rounded to 28,000
\n-21,496 is rouned to 21,000
\n\u2234 Estimated difference = 7,000
\nActual answer = 28,292 – 21496
\n= 6,796<\/p>\n

Question 2.
\nGive a rough estimate (by round off to nearest hundreds) and also a closer estimate (by’rounding off to nearest tens):
\n(a) 439 + 334 + 4,317
\n(b) 1,08,734- 47,599
\n(c) 8,325 – 491
\n(d) 4,89,348 – 48,365.
\nMake four more of such examples.
\nSolution:
\nTo begin with, we round off to thousands.
\n439 rounds to 0
\n334 rounds to 0
\nand 4,317 rounds to 4,000
\nRough estimated sum= 0 + 0 + 4,000
\n= 4,000
\nThis is not a reasonable estimate.
\nActual sum = 439 + 334 + 4,317 = 5,090.
\nTo get a closer estimate, let us try rounding off each number to hundreds.
\n\"HBSE<\/p>\n

\"HBSE<\/p>\n

(b) To begin with, we round off to ten thousands.
\n\"HBSE
\nActual difference = 1,08,734 – 47,599 = 61135
\nTo get a closer estimate, let us try rounding off each number to hundreds.
\n\"HBSE<\/p>\n

(c) To begin with, we round off to hundreds
\n\"HBSE
\nActual difference = 8,325 – 491 = 7,834
\nTo get a closer estimate let us try rounding off each number to tens.
\n\"HBSE
\nThis is a better and more meaningful estimate.<\/p>\n

\"HBSE<\/p>\n

(d) To begin with, we round off to ten thousands
\n\"HBSE
\nActual difference = 4,89,348 – 48,365
\n= 4,40,983
\nTo get a closer estimate, let us try rounding off each number to thousands.
