Unit conversion and dimensional analysis, based on equivalent ratios, can solve real-world problems. They help in practical scenarios, like converting cooking measurements or understanding distances in different countries. The metric system, based on powers of 10, is particularly convenient for such conversions.
Conversion of measurements, also known as unit conversion and dimensional analysis, can help solve real-world problems in various practical scenarios. For example, a person reading a European cookbook in the United States might require conversion of quantities expressed in liters into cups. Likewise, a Canadian tourist driving through the U.S. might need to convert miles on road signs into kilometers to gauge distances accurately.
It's crucial to understand that a ratio of two equivalent quantities expressed with different measurement units can be used as a unit conversion factor. Suppose, the lengths of 2.54 cm and 1 in are equivalent, so you can derive a conversion factor from this ratio. Various other commonly used conversion factors can make this process easier in daily life, such as converting a basketball player's vertical jump from inches to centimeters or converting cooking measurements.
The metric system is particularly convenient for unit conversion as it is based on powers of 10, so conversions between metric units can be done by simply moving the decimal place. However, dimensional analysis and unit conversion are universally applicable tools that can make life easier, from understanding distances to making recipes to making scientific calculations.

sqrt(-49) / [ (7-2i) - (4+9i) ]
= 7i / (3 - 11i)
= 7i (3+11i) / [ (3 - 11i) (3 + 11i) ]
= (21 i - 77) / (9 + 121) = choice (d), (-77 + 21i) / 130
