5000<\/strong><\/p>\n\n\n\n<p class=\" eplus-wrapper\">A benchmark number is usually a multiple of 10, 100, 1000, etc., or a number having 0 at the ones place or any other decade number, such as 1, 20, 30, 40, etc.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Let\u2019s take a look at examples and non-examples of benchmark numbers.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full
