Answer 1

Answer:

1) 423 x 158

423 rounded to nearest hundreds is 400

158 rounded to nearest hundreds is 200

Estimated Product = 400 x 200 = 80000

2) 271 estimated to the nearest hundred = 300

339 estimated to the nearest hundred = 300

∴ The required estimation = (300 × 300) = 90000

3) 376×123

Estimated value to the nearest hundreds of 376=400

Estimated value to the nearest hundreds of 123=100

∴ required estimation =(400×100)=40000

4) 509×179

Estimated value to the nearest hundreds of 509=500

Estimated value to the nearest hundreds of 179=200

∴ required estimation =(500×200)=100000

5) 264×147

Estimated value to the nearest hundreds of 264=300

Estimated value to the nearest hundreds of 147=100

∴ required estimation =(300×100)=30000

6). 392 estimated to the nearest hundred = 400

138 estimated to the nearest hundred = 100

∴ The required estimation = (400 × 100) = 40000
