Completing a calculation with dimensional analysis is often confused with completing the conversion with missing-value proportions.
Which of the following are true with respect to completing a conversion with dimensional analysis? Select all that apply.
When setting up a conversion with dimensional analysis, I should be sure unwanted units "cancel" (i.e., they are placed in opposite sides of conversion factors; numerator-numerator or denominator-numerator).
When setting up a conversion with dimensional analysis, I should be sure unwanted units "align" (i.e., they are located on the same side of conversion factors; numerator-numerator or denominator-denominator)
After the dimesional analysis calculation is set up, I cross-multiply so that I am multiplying numerators and denominators.
Dimensional analysis should have equal signs ( = ) between converion factors.
After the dimesional analysis calculation is set up, I multiply all of the numerators together and all of the denominators together.
Dimensional analysis should have multiplication symbols ( \times ) between converion factors.
