So we multiply<br \/>\nthe numerator and denominator of one fraction by the same number,<br \/>\nso both fractions will have the same denominator.<br \/>\nFor example, if 5\/12 and 1\/3 are being compared,<br \/>\n1\/3 should be multiplied by 4\/4. It does not change the value of<br \/>\n1\/3 to be multiplied by 4\/4 (which is equal to 1) because any number<br \/>\nmultiplied by 1 is still the same number.<br \/>\nAfter the multiplication (1\/3 * 4\/4 = 4\/12),<br \/>\nthe comparison can be made between 5\/12 and 4\/12.<br \/>\nWe may have to multiply both fractions by different numbers<br \/>\nto produce the same denominator for both fractions.<br \/>\nFor example if 2\/3 and 3\/4 are compared, we need to<br \/>\nmultiply 2\/3 by 4\/4 to give 8\/12 and multiply 3\/4 by 3\/3 to give 9\/12.<br \/>\nThe fraction 3\/4 which is equal to 9\/12 is larger than 2\/3 which is equal to 8\/12.<br \/>\nThe fraction with the larger numerator is the larger fraction if the<br \/>\ndenominators are the same.<br \/>\n<strong><br \/>\nEnvision STEM Project: Senses<\/strong><br \/>\nDo Research Use the Internet or other resources to find information<br \/>\nabout how animals use special senses, such as echolocation,<br \/>\nelectricity, or magnetism.
