I'll guess "polar"
Integers.
910213 is an integer and not a fraction nor mixed number. There is, therefore, no decimal portion..
The decimal fraction is 972/10000 which can be simplified, if required.
0.125 is the decimal of 1/8
There are no such numbers since all integers are also decimal numbers. A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point or any digits after a decimal point.
A decimal number would be between 0 and 1. It represents a fraction, or portion, of 1.
The whole number (if any) remains the same. The decimal portion gets divided by 100 and written as a fraction (x/100) where x=decimal portion. Ex: 1.40 would become 1 40/100 or 1 2/5 after being reduced. So the model would look like this written out: (whole number) (decimal portion)/100
The difference between a positive shear and a negative shear is the direction the beam is distorted into. A force that tends to shear the left portion of the beam upward with respect to the right portion is said to produce a positive shearing force.
"Dose" is a measured portion of a medicine. I am not aware of any exponents that have anything to do with measured quantities of medication! A negative exponent is simply the reciprocal of the corresponding positive exponent. Thus x^(-a) = (1/x)^a for non-zero x.
the decimal portion of 176.261 is 261
The term fraction means a part of the whole. So one half (1/2) is a fraction. The decimal 0.5 means a half and is also a fraction.
The fractional portion is 0.261
