question 7 of 12
a technician needs $\frac{3}{4}$ of a fecal specimen to run an analysis. if the specimen weighs $\frac{2}{3}$ oz., how much will the sample weigh?

1. 2 oz
2. $\frac{1}{2}$ oz
3. $\frac{8}{9}$ oz
4. $\frac{9}{8}$ oz

Explanation:

Step1: Identify the operation

We need to find $\frac{3}{4}$ of $\frac{2}{3}$ oz, which means multiplication.

Step2: Multiply the fractions

$\frac{3}{4}\times\frac{2}{3}=\frac{3\times2}{4\times3}$
Simplify the fraction: $\frac{6}{12}=\frac{1}{2}$

Answer:

B. $\frac{1}{2}$ oz
