Note in the third column:&nbsp;if you want to convert the decimals to percentages, just move the decimal two places to the right.<br \/>\nAnother method for converting fractions to decimals is to manipulate the fraction so that the denominator is 10 or 100 (or any power of 10). After all, percents are fractions of 100.<br \/>\nHere are&nbsp;a few simple examples:<br \/>\n<div  class=\"togglecontainer    avia-builder-el-1  el_after_av_table  el_before_av_hr \" >\n<section class=\"av_toggle_section\"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\"  >    <div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  >        <p data-fake-id=\"#toggle-id-1\" class=\"toggler activeTitle\"  itemprop=\"headline\"    role=\"tab\" tabindex=\"0\" aria-controls=\"toggle-id-1\">Example 1<span class=\"toggle_icon\" >        <span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p>        <div id=\"toggle-id-1\" class=\"toggle_wrap active_tc\"  style='display:block;'>            <div class=\"toggle_content invers-color \"  itemprop=\"text\"   ><p>Convert \u00bd to a decimal by manipulating the denominator to a power of 10.<\/p>\n            <\/div>        <\/div>    <\/div><\/section>\n<section class=\"av_toggle_section\"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\"  >    <div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  >        <p data-fake-id=\"#toggle-id-2\" class=\"toggler \"  itemprop=\"headline\"    role=\"tab\" tabindex=\"0\" aria-controls=\"toggle-id-2\">Conversion<span class=\"toggle_icon\" >        <span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p>        <div id=\"toggle-id-2\" class=\"toggle_wrap \"  >            <div class=\"toggle_content invers-color \"  itemprop=\"text\"   ><p>Convert the fraction 1\/2 to 5\/10 by just multiplying by 5.
