for 2/3 just dvide by 6, 24/36 just multiply both terms by 2 and for 6/9 just divide by 2</span>
Answer:
160
Step-by-step explanation:
77 / 48 = 1.604
1.604 x 100 = 160.41 which is about 160 passengers in total.
This is not true. The infinite series

converges if and only if the sequence of its partial sums converges. The

-th partial sum is

but clearly this diverges as

gets arbitrarily large.
