The term \u201cpercent\u201d comes from the Latin <em>per centum<\/em>, which means \u201cby the hundred.\u201d When you are given a percentage, like 40%, it can be converted to a fraction or decimal for calculation purposes. In this case, 40% is equal to 40 divided by 100, which is 0.4.<\/p>\n\n\n\n<p>The problem asks us to find the value of <strong>x<\/strong> in the equation where 40% is equal to <strong>x<\/strong> divided by 30. This is a basic proportion problem. Proportions compare two ratios or fractions. In this example, 40% (or 0.4) is the same as <strong>x\/30<\/strong>. The goal is to find the number that, when divided by 30, gives us 0.4.<\/p>\n\n\n\n<p>To isolate <strong>x<\/strong>, we use the principle of cross multiplication or multiply both sides of the equation by 30. This is because multiplying both sides of an equation by the same number keeps the equation balanced. So:<\/p>\n\n\n\n<p><strong>0.4 \u00d7 30 = x<\/strong><\/p>\n\n\n\n<p>Multiplying 0.4 by 30 gives 12. That tells us <strong>x<\/strong> must be 12 for the equation to be true.<\/p>\n\n\n\n<p>To check your work, substitute x = 12 back into the original equation:<\/p>\n\n\n\n<p><strong>12 \/ 30 = 0.4<\/strong>, which is 40%, so the solution is correct.<\/p>\n\n\n\n<p>This type of question is common in problems involving percentages, ratios, or proportions. Understanding how to manipulate equations and convert percentages can help you solve them accurately and efficiently.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"722\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-135.jpeg\" alt=\"\" class=\"wp-image-27830\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-135.jpeg 722w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-135-212x300.jpeg 212w\" sizes=\"auto, (max-width: 722px) 100vw, 722px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>If 40% is equal to the fraction x\/30 .What is the value of x The Correct Answer and Explanation is: To solve the equation: 40% = x \/ 30 First, convert 40% into a decimal or a fraction.We know that: 40% = 40 \u00f7 100 = 0.4 So we now rewrite the equation: 0.4 = [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-27825","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/27825","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=27825"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/27825\/revisions"}],"predecessor-version":[{"id":27831,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/27825\/revisions\/27831"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=27825"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=27825"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=27825"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
