Question

a biologist studied how cells grow by adding liquid protein to cell samples. she reported in her study that she divided 4/5 of an ounce of liquid protein evenly among 8 cell samples. how much liquid protein did she give to each cell sample?
write your answer as a fraction or as a whole or mixed number.
______ ounces.

Explanation:

Step1: Understand the problem

We need to divide the total amount of liquid protein, which is $\frac{4}{5}$ of an ounce, evenly among 8 cell samples. This means we have to perform the division $\frac{4}{5} \div 8$.

Step2: Recall the division rule for fractions

Dividing by a number is the same as multiplying by its reciprocal. So, $\frac{4}{5} \div 8 = \frac{4}{5} \times \frac{1}{8}$.

Step3: Multiply the fractions

Multiply the numerators and the denominators: $\frac{4 \times 1}{5 \times 8} = \frac{4}{40}$.

Step4: Simplify the fraction

Simplify $\frac{4}{40}$ by dividing both the numerator and the denominator by their greatest common divisor, which is 4. So, $\frac{4 \div 4}{40 \div 4} = \frac{1}{10}$.

Answer:

$\frac{1}{10}$
