Hey there!
Question :-
[tex]310 + ( -720)[/tex]
We need to solve this arithmetic expression,as a fraction.
Solution:-
[tex] \sf \longmapsto310 \: + ( - 720)[/tex]
Note that (+) and (-) equals to (-).
New Arithmetic expression will be :-
[tex]\sf \longmapsto310 + (720)[/tex]
Remove the parenthesis :-
[tex]\sf \longmapsto310 - 720[/tex]
Calculating the Subtraction:-
[tex]\sf \longmapsto310 - 720[/tex]
As 310 < 720, 720 contains (-) sign. Therefore, The Solution will be -410 not 410.
[tex]\sf \longmapsto - 410[/tex]
Converting to Fraction:-
[tex]\sf \longmapsto \: - 410[/tex]
[tex]\sf \longmapsto \: \dfrac{410 \times 1}{1 \times 1} [/tex]
[tex]\sf \longmapsto - \dfrac{410}{1} [/tex]
On Simplification of this Fraction:-
[tex]\sf \longmapsto \cancel \dfrac{ - 410}{1} [/tex]
On Cancelling , -410 Is the result.
[tex]\sf \longmapsto - {410} [/tex]
______________________________________
Henceforth , the answer of the arithmetic expression Will be :-(Simplified)
[tex]\boxed{\bf-{410} }[/tex]
