Question

simplify both in step by step ​

Answer 1

Step-by-step explanation:

solution (I). {(-8) × 1/5} + [6/11 - ( -1/11)] - {-3/5 × 1/7}

= -8/5 + [6/11 + 1/11] + 3/35

= -8/5 + [(6+1)/11] + 3/35

= -8/5 + 7/11 + 3/35

= (-616 + 245 + 33)/385

= (-616 + 278)/385

= -338/385 Ans.

solution (ll). [(-5)/6 - 1/3]/[2/3 - 6/5]

= [(- 5 - 2)/6]/[(- 10 - 18)/15]

= (-7/6)/(-8/15)

= (-7/6) × (15/-8)

= 35/16

= 2.25 Ans.
