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
