This means that for every 16 grams you consume, you get 130 calories of energy. Since the relationship is directly proportional, if you consume more grams of this food, you will also consume more calories in the same ratio.<\/p>\n\n\n\n<p>To find out how many grams provide <strong>2150 calories<\/strong>, we use the <strong>proportion method<\/strong>. In proportions, two ratios are set equal to each other. The ratio of grams to calories in the first known situation is the same as the ratio in the unknown situation. We set up the proportion:<\/p>\n\n\n\n<p>[<br>\\frac{16}{130} = \\frac{x}{2150}<br>]<\/p>\n\n\n\n<p>This tells us that ( x ), the unknown number of grams, will give us 2150 calories if the food continues to provide calories at the same rate. Using <strong>cross-multiplication<\/strong>, we solve for ( x ), resulting in ( x = 264.6 ) grams.<\/p>\n\n\n\n<p>This approach can be applied in real-life nutrition planning\u2014especially useful for dietitians and health-conscious individuals tracking calorie intake. It helps ensure a person can meet a calorie target while managing portion sizes accurately.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>16.0 grams of a certain food contain 130 calories.
