Let&#8217;s convert this to inches to verify:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 yd = 36 in<\/li>\n\n\n\n<li>3 ft = 36 in<\/li>\n\n\n\n<li>8 in = 8 in<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Total inches = 36 + 36 + 8 = 80 inches.

So &#8220;1 yd 3 ft 8 in&#8221; is less standard \u2014 it mixes yards and feet awkwardly because the 3 ft could be counted as another yard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Option b, &#8220;2 yd 8 in,&#8221; is cleaner because 2 yards + 8 inches is straightforward.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Final conclusion:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Correct answer:<\/strong><br><strong>b. 2 yd 8 in.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation (300 words):<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When converting inches into a combined measurement using yards, feet, and inches, it\u2019s essential to use the relationship between the units clearly. Since 1 foot equals 12 inches, and 1 yard equals 3 feet (or 36 inches), any total number of inches can be expressed in these units by sequential division.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Given 80 inches, first convert to yards: 80 divided by 36 equals 2 yards with a remainder. Two yards equal 72 inches, so the remainder is 8 inches. This gives the expression 2 yd 8 in. This is a clean and standard way to express the measurement, especially when the remainder is less than 1 yard or 1 foot.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Option a, 1 yd 3 ft 8 in, while mathematically correct because 1 yard (36 in) + 3 feet (36 in) + 8 inches = 80 inches, is less standard since &#8220;3 feet&#8221; is itself equal to 1 yard. So, writing &#8220;1 yd 3 ft&#8221; is redundant and could be simplified to 2 yd. Thus, the clearer and more typical notation would be 2 yd 8 in.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Option d, 6 ft 10 in, is close but incorrect because 6 feet 10 inches equals 82 inches, which is 2 inches more than 80.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Option c, 2 yd 8 ft, doesn\u2019t make sense because 8 feet exceed the length of 1 yard (3 feet), and it\u2019s not standard to combine yards and more than 3 feet this way without converting to yards fully.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In everyday measurements, expressing length as feet and inches (such as 6 ft 8 in) is most common. But if yards are preferred, then 2 yd 8 in is a clear, concise, and correct expression of 80 inches.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/05\/image-100.png\" alt=\"\" class=\"wp-image-217899\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Express 80 inches in standard notation using feet and inches.
