To convert Sally&#8217;s weight from kilograms to pounds, we multiply her mass by this conversion factor:<\/p>\n\n\n\n<p>[<br>\\text{Sally&#8217;s weight in pounds} = 70 \\, \\text{kg} \\times 2.205 \\, \\text{pounds\/kg} = 154.35 \\, \\text{pounds}<br>]<\/p>\n\n\n\n<p>So, Sally weighs approximately 154.35 pounds.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Calculate Sally&#8217;s Weight as a Percentage of Dave&#8217;s Weight<\/h3>\n\n\n\n<p>We are also told that Dave weighs 170 pounds. To find out what percentage Sally\u2019s weight is of Dave\u2019s weight, we use the formula for percentage:<\/p>\n\n\n\n<p>[<br>\\text{Percentage} = \\left( \\frac{\\text{Sally&#8217;s weight}}{\\text{Dave&#8217;s weight}} \\right) \\times 100<br>]<\/p>\n\n\n\n<p>Substituting the values we know:<\/p>\n\n\n\n<p>[<br>\\text{Percentage} = \\left( \\frac{154.35 \\, \\text{pounds}}{170 \\, \\text{pounds}} \\right) \\times 100 = 0.906 \\times 100 = 90.6\\%<br>]<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Round the Result<\/h3>\n\n\n\n<p>Since the problem asks for the answer to be rounded to the nearest whole percentage point, we round 90.6% to 91%.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Final Answer:<\/h3>\n\n\n\n<p>Sally\u2019s weight is <strong>91%<\/strong> of Dave\u2019s weight.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>This problem involves basic unit conversion and percentage calculation. We first converted Sally&#8217;s mass in kilograms to weight in pounds using the conversion factor (2.205 pounds per kilogram). After obtaining Sally&#8217;s weight in pounds, we compared it to Dave&#8217;s weight in pounds using a percentage formula. This allowed us to determine the relative weight of Sally compared to Dave. Finally, the result was rounded to the nearest whole number as per the problem&#8217;s instructions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sally has a mass of 70 kilograms and Dave weighs 170 pounds.
