Answer:
8 / 9
Step-by-step explanation:
2 / 3 . 1 / 6 + 1 5 / 9 + 2 ( -7 / 18 )
= 1 / 9 + 14 / 9 - 14 / 18 ( 2 /3 * 1 / 6 = 1 / 3 * 1 / 3 = 1 / 9,
( converting mixed fraction to proper fraction )
( multiplying 2 to -7 / 18 )
= 1 / 9 + 14 / 9 - 7 / 9 ( Making the denominator the same by dividing -14 / 18 by 2)
= 15 / 9 - 7 / 9
= 8 / 9
