Question

a train arrives at the station with 150 passenger's on board . 2/5 of the passengers get off the train in Seattle, and then 35 passengers board the train. how many passengers are on the train when it leaves the station

Answer 1

First, We Have Find What Two Fifths Of 150. So, Divide 150 By Five To Find 1/5 Of 150. 
150 ÷ 5 = 30.
 
Now, To Find 2/5 Of 150, Multiply 30 By Two. So:
30 * 2 = 60
So, 60 = 2/5 of 150.

So, subtract 60 from 150. 
150 - 60 = 90.

So, now we need to add 35, because 35 people get back on. 

90 + 35 = 125

There are 125 passengers when the train leaves.
