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} (20)/(50)\cdot100\%=(2)/(5)\cdot100\%=(2\cdot100\%)/(5)=2\cdot(100\%)/(5)=2\cdot20\%=40\% \\ \end{gathered}`

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