Answer :
To calculate the amount of bacteria in feces, you calculate 30% of 325 g, which is equal to (b) 97.5 g of bacteria per day. Hence, (b) is the correct option.
If an average homo sapiens produces 325 g of feces per day and 30% of it consists of bacteria, to find out how many grams of bacteria a person's feces consists of per day, one can use the following calculation:
- Calculate 30% of 325 g.
To calculate percentage, you multiply the total amount by the percentage (in decimal form). So,
- Convert the percentage into decimal: 30% = 0.30.
- Multiply this decimal by the total weight of the feces: 0.30 times 325 g.
- Perform the multiplication: 0.30 imes 325 g = 97.5 g.
Therefore, the weight of the bacteria in the feces per day is 97.5 g. The correct answer is (b) 97.5g.
