Answers
Step-by-step explanation:
(i) 336 and 782
336 to the nearest hundred = 300 and,
782 to the nearest hundred = 800
∴ Required sum = (300+800) = 1100
(ii) 546 and 342
342 to the nearest hundred = 300
∴ Required sum = (500+300) = 800
Required sum = (500+300) = 800(iii) 270 and 495
Required sum = (500+300) = 800(iii) 270 and 495270 to the nearest hundred = 300 and,
Required sum = (500+300) = 800(iii) 270 and 495270 to the nearest hundred = 300 and,495 to the nearest hundred = 500
Required sum = (500+300) = 800(iii) 270 and 495270 to the nearest hundred = 300 and,495 to the nearest hundred = 500∴ Required sum = (300+500) = 800
Required sum = (500+300) = 800(iii) 270 and 495270 to the nearest hundred = 300 and,495 to the nearest hundred = 500∴ Required sum = (300+500) = 800(iv) 4280 and 5295
Required sum = (500+300) = 800(iii) 270 and 495270 to the nearest hundred = 300 and,495 to the nearest hundred = 500∴ Required sum = (300+500) = 800(iv) 4280 and 52954280 to the nearest hundred = 4300 and,
5295 to the nearest hundred = 5300
5295 to the nearest hundred = 5300∴ Required sum = (4300+5300) = 9600
5295 to the nearest hundred = 5300∴ Required sum = (4300+5300) = 9600(v) 4230 and 2410
5295 to the nearest hundred = 5300∴ Required sum = (4300+5300) = 9600(v) 4230 and 24104230 to the nearest hundred = 4200 and,
5295 to the nearest hundred = 5300∴ Required sum = (4300+5300) = 9600(v) 4230 and 24104230 to the nearest hundred = 4200 and,2410 to the nearest hundred = 2400
5295 to the nearest hundred = 5300∴ Required sum = (4300+5300) = 9600(v) 4230 and 24104230 to the nearest hundred = 4200 and,2410 to the nearest hundred = 2400∴ Required sum = (4200+2400) = 6600
5295 to the nearest hundred = 5300∴ Required sum = (4300+5300) = 9600(v) 4230 and 24104230 to the nearest hundred = 4200 and,2410 to the nearest hundred = 2400∴ Required sum = (4200+2400) = 6600(vi) 30047 and 39287
5295 to the nearest hundred = 5300∴ Required sum = (4300+5300) = 9600(v) 4230 and 24104230 to the nearest hundred = 4200 and,2410 to the nearest hundred = 2400∴ Required sum = (4200+2400) = 6600(vi) 30047 and 3928730047 to the nearest hundred = 30000 and,
5295 to the nearest hundred = 5300∴ Required sum = (4300+5300) = 9600(v) 4230 and 24104230 to the nearest hundred = 4200 and,2410 to the nearest hundred = 2400∴ Required sum = (4200+2400) = 6600(vi) 30047 and 3928730047 to the nearest hundred = 30000 and,39287 to the nearest hundred = 39300
5295 to the nearest hundred = 5300∴ Required sum = (4300+5300) = 9600(v) 4230 and 24104230 to the nearest hundred = 4200 and,2410 to the nearest hundred = 2400∴ Required sum = (4200+2400) = 6600(vi) 30047 and 3928730047 to the nearest hundred = 30000 and,39287 to the nearest hundred = 39300∴ Required sum = (30000+39300) = 69300
