Question

The human body needs about 50 grams of protein daily. A hamburger contains about 20 grams of protein. What percent of the daily needs is the protein in the hamburger?

Answer 1

To answer this question, we can proceed as follows:

1. We have that the total of protein the human body needs daily is 50 grams.

2. A hamburger contains about 20 grams of protein.

Then, to find the asked percent, we can proceed as follows:

$\begin{gathered} \frac{20}{50}\cdot100\%=\frac{2}{5}\cdot100\%=\frac{2\cdot100\%}{5}=2\cdot\frac{100\%}{5}=2\cdot20\%=40\% \\ \end{gathered}$

Therefore, the hamburger has 40% of the protein we need daily.
