In this case, the denominators are 8 and 2. The LCD is the smallest number that both 8 and 2 divide into evenly.<\/p>\n\n\n\n<p>Begin by listing a few multiples of each denominator:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Multiples of 8: 8, 16, 24, 32, 40, &#8230;<\/li>\n\n\n\n<li>Multiples of 2: 2, 4, 6, 8, 10, 12, &#8230;<\/li>\n<\/ul>\n\n\n\n<p>The smallest number common to both lists is 8. Therefore, 8 is the least common denominator.<\/p>\n\n\n\n<p>Next, convert each fraction so that it has a denominator of 8.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The fraction <strong>3\/8<\/strong> already has 8 as its denominator, so it remains unchanged.<\/li>\n\n\n\n<li>The fraction <strong>1\/2<\/strong> must be converted to an equivalent fraction with 8 as the denominator. Since 2 \u00d7 4 = 8, multiply both the numerator and denominator of 1\/2 by 4:<\/li>\n<\/ul>\n\n\n\n<p>1\/2=(1\u00d74)\/(2\u00d74)=4\/81\/2 = (1 \u00d7 4)\/(2 \u00d7 4) = 4\/81\/2=(1\u00d74)\/(2\u00d74)=4\/8<\/p>\n\n\n\n<p>Now both fractions\u20143\/8 and 4\/8\u2014have the same denominator. This makes addition, subtraction, or comparison of the fractions easier.<\/p>\n\n\n\n<p>The importance of using the least common denominator lies in its efficiency. By choosing the smallest shared multiple of the denominators, calculations become simpler and require less simplification afterward. Using a larger common denominator, such as 16 or 32, would still work but would involve unnecessary steps and possible reduction later.<\/p>\n\n\n\n<p>In summary, the least common denominator of 3\/8 and 1\/2 is 8. Converting both fractions to have this denominator allows for straightforward comparison or arithmetic operations. This technique is essential in handling problems involving fractions with different denominators.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-636.jpeg\" alt=\"\" class=\"wp-image-235706\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Find the least common denominator (LCD) of 3\/8 and 1\/2 The Correct Answer and Explanation is: The least common denominator (LCD) of 3\/8 and 1\/2 is 8.
