The quantity that represents units in a value is typically referred to as the "magnitude" or "size" of that value. In mathematical terms, this can be expressed as the absolute value, which denotes the distance of a number from zero on a number line, regardless of its sign. In various contexts, such as physics or finance, units may also refer to specific measurements like meters, dollars, or other defined quantities that help convey the scale or amount of a value.
It represents 8 units
A variable is usually used for that - for example, a single letter that represents the unknown quantity.
The 9 in 879 represents nine ones or nine units
+4 and -4 both do.
In the number 45, the digit 5 represents the units or ones place, meaning it contributes a value of 5. The overall value of the number 45 is composed of both the tens place (4, which represents 40) and the units place (5). Thus, while 5 itself has a value of 5, it is part of the larger number that totals 45.

Since the 8 is in the units column, the 8 simply represents 8 units or 8.
It represents 7 ones or 7 units
The digit 3 in the number 3.026 represents three units.
The 5 in the number 45.37 represents 5 units.
The 9 in 879 represents nine ones or nine units
+4 and -4 both do.
A ratio that's used to convert units always has the value of ' 1 ' with no units. If it were anything different, then you could not multiply it or divide it by any quantity without changing the value of the quantity, which is a basic no-no.
In the number 45, the digit 5 represents the units or ones place, meaning it contributes a value of 5. The overall value of the number 45 is composed of both the tens place (4, which represents 40) and the units place (5). Thus, while 5 itself has a value of 5, it is part of the larger number that totals 45.
The digit 6 in the number 36.5 represents 6 units, or just 6.
