In 100 grams of sweet peas there are 14.5 carbohydrates,5.7 grams of sugars,5.1 grams of dietary fiber, 5.4 grams of protein and 0.4 grams of fat what is the percent composition of each?

Percent composition is the quantity or number of parts of a component contained in 100 parts of the total.

Given the the total is 100 g, the reported quantities for each component are the same percent.

Then, the percent composition of each as part of the entire sweet peas is:

Carb: 14.5%
Sugar: 5.7%
Diet. fiber: 5.1%
Prot: 5.4%
Fat: 0.4%

The rest to make the 100% is supposed to be water.

You could also find the percent composition in dry basis, which is done in this way (this is not what the question asks but it is good to know it).

Total components without water: 14.5 + 5.7 + 5.1 + 5.4 + 0.4 = 31.1 grams

Now divide each content by the total (31.1) and multiply by 100.

I will do one example:

Carbs: [14.5 / 31.1 ] * 100 = 46.6%
