    Answer:

    hope this will help you

    Step-by-step explanation:

    Estimate the following products using general rule:

    (a) 578 × 161 (b) 5281 × 3491 (c) 1291 × 592 (d) 9250 × 29

    Solution (a)

    578 x 161

    Rounding off 578 to the nearest hundreds, we get 600

    And, rounding off 161 to the nearest hundreds, we get 200

    Therefore, 600 x 200 = 1,20,000

    It means that estimate of 578 x 161 is equal to 1,20,000 according to the general rule.

    Solution (b)

    5281 × 3491

    Rounding off 5,291 to the nearest thousands, we get 5,000

    And, rounding off 3,491 to the nearest hundreds, we get 3,500

    Therefore, 5,000 x 3,500 = 1,75,00,000

    It means that estimate of 5281 x 3491 is equal to 1,75,00,000 according to the general rule.

    Solution (c)

    1291 × 592

    Rounding off 1291 to the nearest hundreds we get, 1300

    And, rounding off 592 to the nearest hundreds, we get 600

    Therefore, 1300 x 600 = 7,80,000

    It means that estimate of 1291 x 592 is equal to 7,80,000 according to the general rule.

    Solution (d)

    9250 × 29

    Rounding off 9250 to the nearest thousands, we get 9000

    And, rounding off 29 to the nearest tens, we get 30

    Therefore, 9000 x 30 = 2,70,000

    It means that estimate of 9250 × 29 is equal to 2,70,000 using general rule.
