If not, don\u2019t worry.<\/p>\n<p>In order to take the reciprocal of a fraction, we switch the roles of the numerator and the denominator.<\/p>\n<p>Here are some quick examples:<\/p>\n<p>The reciprocal of 2\/3 is 3\/2.<\/p>\n<p>The reciprocal of 4\/5 is 5\/4.<\/p>\n<p>The reciprocal of 1\/7 is 7\/1 = 7.<\/p>\n<p>Now that we know what the reciprocal of a fraction is, let\u2019s look at how we can change a division question with fractions which we might not be able to answer into a multiplication question using fractions which we will be able to answer.<\/p>\n<p>Remember: Dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.<\/p>\n<p>Here are some examples:<\/p>\n<p>1\/4 \u00f7 2\/4 = 1\/4 x 4\/2<\/p>\n<p>2\/3 \u00f7 2\/4 = 2\/3 x 4\/2<\/p>\n<p>2\/6 \u00f7 3\/5 = 2\/6 x 5\/3<\/p>\n<p>&nbsp;<\/p>\n<p>Now, we will work all the way through an example of how to divide fractions.<\/p>\n<p><strong>Example 2:<\/strong> 4\/5 \u00f7 1\/3<\/p>\n<p><em><span style=\"text-decoration: underline\">Step One:<\/span> <\/em>Change the division question into a multiplication question, by multiplying by the reciprocal.<\/p>\n<p>4\/5 \u00f7 1\/3 = 4\/5 x 3\/1<\/p>\n<p><em><span style=\"text-decoration: underline\">Step Two:<\/span><\/em> Multiply the numerators together to get the new numerator.<\/p>\n<p>4\/5 x 3\/1 = (4 x 3)\/ ? = 12\/?<\/p>\n<p><em><span style=\"text-decoration: underline\">Step Three<\/span><\/em>: Multiply the denominators together to get the new denominator.<\/p>\n<p>4\/5 x 3\/1 = 12\/ (5 x 1) = 12\/5<\/p>\n<p><em><span style=\"text-decoration: underline\">Step Four:<\/span><\/em> If it is possible, simplify the fraction.<\/p>\n<p>The fraction 12\/ 5 is already in simplest form.<\/p>\n<p>Now it is your turn again.<\/p>\n<p>What is 3\/2 \u00f7 1\/4?<\/p>\n<p>&nbsp;<\/p>\n<p>This was written for you by <strong>Mia<\/strong>, one of the tutors with <span class=\"tutorOrange\">Test Prep Academy.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Multiplying Fractions If you are able to multiply whole numbers together then you will be able to multiply fractions.
