If a 2/3 cup serving of cereal provides your full daily value of full look acid than what percent of your daily value of folic acid will you receive in 1/2

Verified Answer :

Write a proportion like 2/3 is to 100% as 1/2 is to X. ( 2/3:100::1/2:X) 

Multiply the centers and divide by the know side. 100 x 1/2 = 50 and 50 divided by 2/3= 75 

So the answer is 75 % of the daily value. 

Maybe in English you call "centers" and "sides" by other names. But I am translating what I learned in another language.

You will receive 75% of your daily value of folic acid  in \(\dfrac12\) cup serving.

Given:

Fraction of serving required for full day value = \(\dfrac{2}3\)

To find:

The percent of daily value you will receive in \(\dfrac12\) cup serving.

Calculation:

The percent of daily value you will receive in \(\dfrac12\) cup serving. = \(\dfrac{\dfrac12}{\dfrac23}\times100\%\)

= \(\dfrac{3}{4}\times100\%\)

\(=3\times25\%\)

\(=75\%\)

Hence, you will receive 75% of your daily value of folic acid  in \(\dfrac12\) cup serving.
