Rewrite both fractions so they have a common denominator:
-3/6 = -21/42
-5/7 = -30/42
Now you have -21/42 - 30/42
Now subtract to get:
-51/42 which reduces to -17/14 = -1 3/14
The simplification of the expression is,-17/14. The simplification is done by applying the mathematical operation step by step.
What does it mean to simplify an expression?
Simplification usually entails doing out the expression's pending processes.
The given expression is
(-3/6) –(5/7)
The LCM of the 6 and 7 is 42 so rewrite the equation as;
(-3×7)/42 – (5×6)/7
(-21/42)-30/42
-51/42
Divide by 3 from the numerator and denominator we get;
-17/14
Hence, the simplification of the expression is,-17/14
