What is the ratio of girls to boys in the class?<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-1-color\">The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Correct Answer:<\/h3>\n\n\n\n<p>The <strong>ratio of girls to boys<\/strong> in the class is <strong>15:13<\/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<\/h3>\n\n\n\n<p>A ratio is a way to compare two quantities using division. It shows how much of one thing there is compared to another. In this case, we are asked to find the ratio of <strong>girls to boys<\/strong> in a class.<\/p>\n\n\n\n<p>We are told:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>There are <strong>15 girls<\/strong>.<\/li>\n\n\n\n<li>There are <strong>13 boys<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>To express the ratio of girls to boys, we write the number of girls <strong>first<\/strong>, followed by the number of boys:Ratio&nbsp;of&nbsp;girls&nbsp;to&nbsp;boys=15:13\\text{Ratio of girls to boys} = 15:13Ratio&nbsp;of&nbsp;girls&nbsp;to&nbsp;boys=15:13<\/p>\n\n\n\n<p>This means that for every 15 girls, there are 13 boys in the class. It&#8217;s important to keep the <strong>order<\/strong> correct. The ratio of <strong>girls to boys<\/strong> is not the same as the ratio of <strong>boys to girls<\/strong>, which would be 13:15.<\/p>\n\n\n\n<p>Ratios can also be expressed as fractions or decimals, but in most cases like this, it&#8217;s best to keep them in the form of two numbers separated by a colon (:), especially when dealing with groups or populations.<\/p>\n\n\n\n<p>Let\u2019s check if the ratio can be simplified. To do that, we see whether both numbers (15 and 13) have a common factor other than 1. Since 15 and 13 share <strong>no common factors<\/strong> other than 1, the ratio <strong>15:13<\/strong> is already in its <strong>simplest form<\/strong>.<\/p>\n\n\n\n<p>This ratio tells us about the <strong>gender distribution<\/strong> in the class. A ratio close to 1:1 would mean an equal number of boys and girls. However, in this case, the ratio 15:13 shows there are slightly more girls than boys. Understanding such ratios helps in analyzing group compositions and making decisions based on proportion and balance.<\/p>\n\n\n\n<p>So, to conclude:<\/p>\n\n\n\n<p><br>The ratio of girls to boys in the class is <strong>15:13<\/strong>, and it is already in its simplest form.<\/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-banner4-618.jpeg\" alt=\"\" class=\"wp-image-228773\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>A class of 28 students has 13 boys and 15 girls.
