-5/6 -1/3 ( lcm of 6, 3 is 6) and 2/3-(6/-5)
= -5-1(2)/6 = 2/3+6/5 (lcm of 3, 5 is 15)
= -5-2/6 = 2(5)+6(3)/15
= -7/6 = 10+18/15
= 28/15
then,
[- 5/6 - 1/3 ] / [2/3 - 6/-5] = [-7/6] / [28/15]
= -7/6 × 15/28
= -1/2 × 5/4
= -5/8
= -0.625
therefore,
[- 5/6 - 1/3 ] / [2/3 - 6/-5] = -0.625
= -5-1(2)/6 = 2/3+6/5 (lcm of 3, 5 is 15)
= -5-2/6 = 2(5)+6(3)/15
= -7/6 = 10+18/15
= 28/15
then,
[- 5/6 - 1/3 ] / [2/3 - 6/-5] = [-7/6] / [28/15]
= -7/6 × 15/28
= -1/2 × 5/4
= -5/8
= -0.625
therefore,
[- 5/6 - 1/3 ] / [2/3 - 6/-5] = -0.625
