You are testing a new sugar replacement that you think is indigestible (and potentially useful in diet products). You feed 1 gra

enyata [817]

Answer: The % digestibility of the sugar alternative is 10.

Explanation:

First we have to know how many grams of the sugar replacement were in the total rat feces. We know 22,5% of the feces were the sugar replacement, so we use cross multiplication for that:

If 20 grams is 100% of the feces, then

x grams / 22.5% = 20grams / 100%

xgrams = (22.5 . 20grams) / 100% = 4.5grams

If each rat ingested 1gram of the sugar replacement, all five rats ate a total of 5grams.

Now we have to check how much of this sugar replacement was digested. If the rats ate 5grams and 4.5grams were present in their feces

5grams - 4.5grams = 0.5grams

This means they digested 0.5grams.

We use cross multiplication again to find out which percentage of the initial sugar replacement this represents.

If 5grams is 100% of the ingested sugar replacement, then

x% / 0.5grams = 100% / 5grams

x% = (0.5grams . 100%) / 5grams = 10%
