This makes the girls the \u201cpart\u201d and the class of 50 the \u201cwhole.\u201d Substituting into the formula:Percentage&nbsp;of&nbsp;girls=(3450)\u00d7100=68%\\text{Percentage of girls} = \\left( \\frac{34}{50} \\right) \\times 100 = 68\\%Percentage&nbsp;of&nbsp;girls=(5034\u200b)\u00d7100=68%<\/p>\n\n\n\n<p>This means that <strong>68% of the class are girls<\/strong>.<\/p>\n\n\n\n<p>To find the percentage of boys in the class, first calculate how many students are boys. Since there are 50 students total and 34 are girls:Number&nbsp;of&nbsp;boys=50\u221234=16\\text{Number of boys} = 50 &#8211; 34 = 16Number&nbsp;of&nbsp;boys=50\u221234=16<\/p>\n\n\n\n<p>Now, calculate what percent 16 is of 50:Percentage&nbsp;of&nbsp;boys=(1650)\u00d7100=32%\\text{Percentage of boys} = \\left( \\frac{16}{50} \\right) \\times 100 = 32\\%Percentage&nbsp;of&nbsp;boys=(5016\u200b)\u00d7100=32%<\/p>\n\n\n\n<p>So, <strong>32% of the class are boys<\/strong>.<\/p>\n\n\n\n<p>Notice that the percentages of girls and boys add up to 100%:68%+32%=100%68\\% + 32\\% = 100\\%68%+32%=100%<\/p>\n\n\n\n<p>This confirms that the calculations are correct, as the total must always equal 100% in problems involving parts of a whole.
