The word "times" means twice as many times. Only quantifiers, length units, area units, unit of volume and unit of volume can be used as units.
For example: Xiaoming has 10 pencils, Xiaogang has 2 pencils, how many times is Xiaoming?
10÷2=5
There is no need to add units after 5.
Mathematically, "unit" refers to the name of the standard quantity to measure things. For example, the units of mass are g, kg and t. When expressing the weight of an object, it is used as a standard. When we describe the mass of an object, we always express it in the form of (numerical value+unit) (for example, an egg 50g), so that everyone can understand and determine the mass of the object. Without units, it is impossible to quantify a thing. Cannot be calculated mathematically.
