In 3/4 cup of oatmeal, that is 1/10 of the recommended daily value of iron. What faction of the daily recommended value of iron is in 1 cup of oatmeal?

Respuesta :

Answer:

recommended value of iron is [tex]\frac{2}{15}[/tex]

Step-by-step explanation:

In 3/4 cup of oatmeal, that is 1/10 of the recommended daily value of iron

The ratio of cup of oatmeal to the value of iron is

[tex]\frac{\frac{3}{4}}{\frac{1}{10} } =\frac{30}{4}[/tex]

Let x be the recommended value of iron for 1 cup of oatmeal

Make a proportion

[tex]\frac{oatmeal}{value} =\frac{oatmeal}{value}[/tex]

[tex]\frac{30}{4} =\frac{1}{x}[/tex]

cross multiply

[tex]30x=4[/tex]

[tex]x=\frac{4}{30}[/tex]

[tex]x=\frac{2}{15}[/tex]

recommended value of iron is 2/15
