Final answer:
The multiplication of whole numbers and fractions requires careful calculation, and results are typically expressed with the correct number of significant figures and, if necessary, in scientific notation.
Step-by-step explanation:
The student's question involves finding the value of simple multiplications and multiplications involving fractions. These calculations are important in various scientific and mathematical contexts, and often involve adhering to rules regarding significant figures and scientific notation.
For each part of the question:
- To find the value of 8*1/3, you simply divide 8 by 3, which equals to about 2.67.
- The value of 8*2/3 is found by multiplying 8 by 2 and then dividing by 3, which equals to about 5.33.
- The value of 164*3/4 requires you to multiply 164 by 3 and then divide by 4, which equals to 123.
When calculating in scientific contexts, it is crucial to express the final answers with the correct number of significant figures and, if needed, in scientific notation.
