The numerator is whats being subtracted or added when you are subtracting or adding a fraction
Only like terms can be added or subtracted. 10m and 1s cannot be added; but divided, 10 m/s becomes a velocity.
no
Because thats how y convert

Prefixes are symbols that are added before a unit to denote a multiple or fraction of that unit, such as kilo for a thousand or milli for a thousandth. Base units are fundamental units of measurement that are used as a reference for other units in a particular system, such as the meter for length or the kilogram for mass in the metric system.
The reason why is that a fraction is a different numbering system than whole numbers. The "whole number" system is based on units of 100. But a fraction is only a part of a whole number, so in order to add or subtract you must make both fractions the same type of unit just like whole numbers. You cannot add 1/6 and 2/24 unless you have the same units...which in this case is 24. So, multiplying the six by 4 will give you 4/24, and now you can add the numerators together because they are in the same "family".
It is the denominator
Nothing happens to the fraction.
What is a fraction in which the numerator and denominator represent the same amount but are in different units?
It is not possible to answer the question because there is no information about the units used for the integer value: 256. It should be obvious to anybody that the fraction for 256 millimetres + 2 inches will be quite different to 256 cm + 2 inches.
A rate is a fraction that compares two quantities measured in different units. If the denominator of the fraction is 1 unit, the rate is called a unit rate.
The fraction is4/(the weight of the whole thing, in pounds) . The fraction is a naked number, without units.
