Answer:
see the explanation
Step-by-step explanation:
we know that
A mixed number is the sum of a integer and a fractional part
we have
[tex]7\frac{1}{5}+(-8\frac{3}{5})[/tex]
so
[tex]7\frac{1}{5}=7+\frac{1}{5}[/tex]
[tex]-8\frac{3}{5}=-8-\frac{3}{5}[/tex]
substitute
[tex]7+\frac{1}{5}+(-8-\frac{3}{5})[/tex]
Group terms
[tex](7-8)+(\frac{1}{5}-\frac{3}{5})[/tex]
[tex](-1)+(-\frac{2}{5})[/tex]
[tex]-1\frac{2}{5}[/tex]
The sum of the integer and fractional parts is -1 and -2/5, respectively. And can be represented as -7/5.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
The expression is given as
[tex]7 \dfrac{1}{5}+ (-8\dfrac{3}{5})[/tex]
The expression can be written as
[tex]\dfrac{36}{5}+ (-\dfrac{43}{5})[/tex]
The sum will be given as
[tex]\rm \rightarrow \dfrac{36}{5}-\dfrac{43}{5}\\\\\rightarrow \dfrac{36-43}{5}\\\\\rightarrow \dfrac{-7}{5}[/tex]
The sum of the integer and fractional parts is -1 and -2/5, respectively.
