Given: i) 3456+89
ii) 312+8655
iii)74862+51824
To find: The sum by suitable estimation by rounding both to the smaller one's level.
Solution:
- Now we have given three terms, so solving one by one each by smaller one's level:
- i) 3456+89:
3000+0 . 400+0 . 50+80 . 6+9
= 3000 + 400 + 130 + 15
= 3545
- Similarly,
ii) 312+8655
8000+0 . 600+300 . 50+10 . 5+2
= 8000 + 900 + 60 + 7
= 8967
- Similarly,
iii) 74862+51824
70000+50000 . 4000+1000 . 800+800 . 60+20 . 2+4
= 120000 + 5000 + 1600 + 80 + 6
= 126686
Answer:
So the value of three terms are: 3545, 8967, 126686
Answer:
So the value of three terms are: 3545, 8967, 126686
Step-by-step explanation:
i) 3456+89:
3000+0 . 400+0 . 50+80 . 6+9
= 3000 + 400 + 130 + 15
= 3545
ii) 312+8655
8000+0 . 600+300 . 50+10 . 5+2
= 8000 + 900 + 60 + 7
= 8967
iii) 74862+51824
70000+50000 . 4000+1000 . 800+800 . 60+20 . 2+4
= 120000 + 5000 + 1600 + 80 + 6
= 126686
