Estimate the product 1391 x 492 by rounding off each number to its nearest hundreds. Please answer. I will follow you.<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To estimate the product of 1391\u00d74921391 \\times 4921391\u00d7492 by rounding each number to the nearest hundred:<\/p>\n\n\n\n

    \n
  1. Round 1391 to the nearest hundred<\/strong>:
    The hundreds digit is 3 (since 1391 is between 1300 and 1400). Since 1391 is closer to 1400 than to 1300, we round it up<\/strong> to 1400.<\/li>\n\n\n\n
  2. Round 492 to the nearest hundred<\/strong>:
    The hundreds digit is 4 (since 492 is between 400 and 500). Since 492 is closer to 500 than to 400, we round it up<\/strong> to 500.<\/li>\n<\/ol>\n\n\n\n

    Now, multiply the rounded numbers:1400\u00d7500=700,0001400 \\times 500 = 700,0001400\u00d7500=700,000<\/p>\n\n\n\n

    Explanation:<\/h3>\n\n\n\n

    Rounding numbers makes calculations easier and quicker, especially when you only need an approximation. Here\u2019s why the steps above are reasonable:<\/p>\n\n\n\n

      \n
    • Rounding<\/strong>: Numbers are rounded to the nearest hundred to simplify the computation. This helps in estimating the product without going into the exact multiplication of the original numbers.<\/li>\n\n\n\n
    • Approximation<\/strong>: Since we rounded both 1391 and 492 to 1400 and 500, respectively, the result is an estimate, not an exact value. The actual product would be a bit less than this because the rounded values are slightly higher than the original numbers.<\/li>\n<\/ul>\n\n\n\n

      Finally, after rounding and multiplying, we get the estimated product of 700,000<\/strong>.<\/p>\n\n\n\n

      The actual product<\/strong> of 1391 and 492 is 684,132. As we can see, the estimate of 700,000 is close to the real answer, which is a great example of how rounding can be a useful tool for fast calculations when precision is not crucial.<\/p>\n\n\n\n
