Question

The Food and Drug Administration (FDA) recommends a certain amount of nutrient intake per day called the “daily value.” Food labels usually show percentages of the daily values for several different nutrients—calcium, iron, vitamins, etc.

In a cup of oatmeal, there is the recommended daily value of iron.





Write a multiplication equation and a division equation to represent the question.

Answer 1

Multiplication Equation:

Let x be the number of cups of oatmeal needed to meet the recommended daily value of iron.

If the daily value of iron is represented by y, then we can write the multiplication equation as:

x * y = 1

This equation means that the total amount of iron obtained from x cups of oatmeal should be equal to the recommended daily value of iron, which is 1.

Division Equation:

Alternatively, we can represent the relationship between the recommended daily value of iron and the amount of iron in a cup of oatmeal using a division equation.

If a cup of oatmeal contains z amount of iron, then the division equation can be written as:

1 / z = y

This equation means that to get the recommended daily value of iron, we need to divide 1 by the amount of iron in one cup of oatmeal. The answer to this division problem will give us the number of cups of oatmeal needed to obtain the recommended daily value of iron.
