Answer:
-13/5 + 12/7 ÷ -13/7 × -1/2 = 62/65
Step-by-step explanation:
-13/5 + 12/7 ÷ -13/7 × -1/2
= (-13 × 7/5 × 7) + (12 × 5/7 × 5) ÷ -13/7 × -1/2
['MINUS' + 'MINUS' = 'PLUS', so both the minus will be cancelled.]
= -91/35 + 60/35 ÷ 13/14
= -31/35 ÷ 13/14
= -31/35 × 14/13
= -31/5 × 2/13
= -31/5 × 2/13
= -62/65
