Given:


(6+4\cdot1-2)/(-5(4-1/(7+5)))

Required:

We need to evaluate the given expression.

Step-by-step explanation:

Use the BODMAS rule.

Solve the bracket.


(6+4\cdot1-2)/(-5(4-1/(7+5)))=(6+4\cdot1-2)/(-5(4-1/12))

Divide 1 by 12.


(6+4\cdot1-2)/(-5(4-1/(7+5)))=(6+4\cdot1-2)/(-5(4-(1)/(12)))

Multiply 4 and 1 gives 4.


(6+4\cdot1-2)/(-5(4-1/(7+5)))=(6+4-2)/(-5(4-(1)/(12)))

Add 6 and 4 gives 10.


(6+4\cdot1-2)/(-5(4-1/(7+5)))=(10-2)/(-5(4-(1)/(12)))

Subtract 2 from 10 given 8.


(6+4\cdot1-2)/(-5(4-1/(7+5)))=(8)/(-5(4-(1)/(12)))
(6+4\cdot1-2)/(-5(4-1/(7+5)))=(8)/(-5(4*(12)/(12)-(1)/(12)))
(6+4\cdot1-2)/(-5(4-1/(7+5)))=(8)/(-5((48-1)/(12)))
(6+4\cdot1-2)/(-5(4-1/(7+5)))=(8)/(-5((47)/(12)))
(6+4\cdot1-2)/(-5(4-1/(7+5)))=(8)/(-((235)/(12)))

Multiply the numerator by the reciprocal of the denominator to divide the rational numbers.


(6+4\cdot1-2)/(-5(4-1/(7+5)))=8*(-12)/(235)
(6+4\cdot1-2)/(-5(4-1/(7+5)))=(-96)/(235)

Final answer:


(6+4\cdot1-2)/(-5(4-1/(7+5)))=(-96)/(235)
