Estimate each of the following products by rounding off each number to the nearest ten:

1. 38 Ã— 63

Solution

Given

38 Ã— 63

Estimated value to the nearest ten of 38 = 40

Estimated value to the nearest ten of 63 = 60

âˆ´ required estimation = (40 Ã— 60) = 2400

2. 54 Ã— 47

Solution

Given

54 Ã— 47

Estimated value to the nearest ten of 54 = 50

Estimated value to the nearest ten of 47 = 50

âˆ´ required estimation = (50 Ã— 50) = 2500

3. 28 Ã— 63

Solution

Given

28 Ã— 63

Estimated value to the nearest ten of 28 = 30

Estimated value to the nearest ten of 63 = 60

âˆ´ required estimation = (30 Ã— 60) = 1800

4. 42 Ã— 75

Solution

Given

42 Ã— 75

Estimated value to the nearest ten of 42 = 40

Estimated value to the nearest ten of 75 = 80

âˆ´ required estimation = (40 Ã— 80)

= 3200

5. 64 Ã— 58

Solution

Given

64 Ã— 58

Estimated value to the nearest ten of 64 = 60

Estimated value to the nearest ten of 58 = 60

âˆ´ required estimation = (60 Ã— 60)

= 3600

6. 15 Ã— 34

Solution

Given

15 Ã— 34

Estimated value to the nearest ten of 15 = 20

Estimated value to the nearest ten of 34 = 30

âˆ´ required estimation = (20 Ã— 30)

= 600

Estimate each of the following products by rounding off each number to the nearest hundred:

7. 376 Ã— 123

Solution

Given

376 Ã— 123

Estimated value to the nearest hundreds of 376 = 400

Estimated value to the nearest hundreds of 123 = 100

âˆ´ required estimation = (400 Ã— 100)

= 40000

8. 264 Ã— 147

Solution

Given

264 Ã— 147

Estimated value to the nearest hundreds of 264 = 300

Estimated value to the nearest hundreds of 147 = 100

âˆ´ required estimation = (300 Ã— 100)

= 30000

9. 423 Ã— 158

Solution

Given

423 Ã— 158

Estimated value to the nearest hundreds of 423 = 400

Estimated value to the nearest hundreds of 158 = 200

âˆ´ required estimation = (400 Ã— 200)

= 80000

10. 509 Ã— 179

Solution

Given

509 Ã— 179

Estimated value to the nearest hundreds of 509 = 500

Estimated value to the nearest hundreds of 179 = 200

âˆ´ required estimation = (500 Ã— 200)

= 100000
