Question
Reading the milk requirements chart and converting cups
Original question: The chart shows the kinds and amounts of foods a person needs regularly.
Foods Required for Good Nutrition
Fruit Group 2-4 servings daily of whole fruit, raw or canned fruit or unsweetened fruit juice
Milk Group 2-3 servings 9-12 yr.-olds: 3 or more cups daily teenagers: 4 or more cups daily adults: 2 or more cups daily (Cheese, ice cream, and yogurt can help fulfill these requirements.)
Meat Group 2-3 servings 5-7 ounces a day of beef, veal, pork, lamb, poultry, fish, shellfish, or eggs or dried beans, peas, nuts, or peanut butter
Vegetable Group 3-5 servings of a dark green or deep yellow vegetable at least every other day; citrus fruit or other fruit or vegetable rich in vitamin C; other fruits and vegetables, including potatoes
Bread and Cereal Group 6-11 servings a day of breads (whole grain or enriched), rolls, cereals, crackers, macaroni, spaghetti, noodles, rice, or grits
Measurement Table 2 cups = 1 pint 2 pints = 1 quart 2 quarts = one half gallon (8 cups) 2 half gallons = one gallon (16 cups)

- At what age does a person require the most milk? If you were going to buy milk for six teenagers for one day, how much would you need? Look at the Foods Required for Good Nutrition chart. Then figure your answer. (6 teenagers x 4 cups = ? cups) Look at the measurement table on the left. Give your answer in the largest amount.
Expert Verified Solution
Key concept: Milk requirements by age group are the key to this chart-based nutrition question, especially when cups must be converted into larger units.
Step by step
Read the chart for the age group
The milk group table says that teenagers need 4 or more cups daily. Since the question asks, “At what age does a person require the most milk?” the largest listed need is for teenagers, who require 4 or more cups each day. Adults need 2 or more cups, and 9- to 12-year-olds need 3 or more cups, so teenagers are the highest among the groups shown.
Multiply the amount for six teenagers
For six teenagers, each needing 4 cups per day, the total is
6 × 4 = 24 cups
So the full amount of milk needed is 24 cups for one day.
Convert cups into the largest unit
The measurement table shows that 2 cups = 1 pint, 2 pints = 1 quart, 2 quarts = 1 half gallon, and 2 half gallons = 1 gallon. Since 16 cups = 1 gallon, the 24 cups can be converted into gallons and cups.
24 cups = 16 cups + 8 cups = 1 gallon + 8 cups
Because 8 cups = 1 half gallon, the largest amount you can use is
If you prefer a single mixed-unit answer, you can also say 1 gallon and 8 cups. Both are correct representations of the same quantity.
Why the unit choice matters
The instruction says to give the answer in the largest amount. That means you should use the biggest unit from the chart that still fits the total cleanly. In this case, gallons are the largest unit listed, so the answer should start with gallons, not cups. Converting in an orderly way avoids losing track of the amount.
The nutrition part and the measurement part work together: first identify the daily serving need, then multiply by the number of people, and finally convert the total into a larger unit.[1][2]
Pitfall alert
A common mistake with this milk chart is reading the adult row instead of the teenager row. The chart is asking for the age group that needs the most milk, and teenagers have the highest listed requirement. Another problem is stopping at 24 cups without converting to the largest unit requested. Because the measurement table includes gallons, the answer should not stay in cups if a larger unit can be used. Students also sometimes confuse half gallons and quarts: 2 quarts make 1 half gallon, and 2 half gallons make 1 gallon. Mixing those conversions can produce an incorrect final unit. Writing the conversions one step at a time prevents the most common errors and makes it easy to check the answer.
Try different conditions
If the chart had said that teenagers need 5 cups daily instead of 4, then six teenagers would need 30 cups in one day. Using the measurement table, 30 cups is 1 gallon (16 cups) plus 14 cups, which is also 1 gallon, 1 half gallon, and 6 cups. If the group changed from six teenagers to eight teenagers at the original rate of 4 cups each, the total would be 32 cups, which equals exactly 2 gallons. These variations show why multiplication and unit conversion must both be done carefully. Changing either the number of people or the daily serving amount changes the final large-unit answer.

FAQ
How do you find the milk needed for six teenagers from the chart?
The chart says teenagers need four cups each day. Multiply four by six to get twenty-four cups, then convert the total into the largest unit listed in the measurement table.
Which age group needs the most milk in the nutrition chart?
Teenagers need the most milk in the chart because their daily requirement is four or more cups. That is greater than the amounts listed for younger children and adults.
