Answer:
649 trains
Step-by-step explanation:
If there are 30 seats per carriage, and there is 18 carriages per train.
You multiple 30 and 18 to get how many seats there are in a train.
30*18 is 540 seats.
To figure out how many trains would be needed to seat 350,000 passenger, you have to divide 350,000 with 540 to get how many trains would be needed.
350,000/540 is 648.1
Since the answer is 648.1 and you can't chop a train into 10 pieces, you would need 649 trains to seat 350, 000 passengers.

Step-by-step explanation:
The solution to the equation can be found by multiplying by the denominator, then dividing by its coefficient.
The missing value in the fraction is 350.

<em>Additional comment</em>
Here, we have rewritten the percentage as a decimal fraction. You could also rewrite it as a ratio of two integer: 22% = 22/100. Sometimes there is confusion about percentages. It can help to think of the % symbol as meaning /100:
22% = 22/100
Of course, that is "twenty-two hundredths" or 0.22.
If you just write the problem using 22/100 for 22%, then you get the proportion ...
22/100 = 77/x
22x = 7700 . . . . . "cross multiply" (multiply by 100x)
x = 7700/22 = 350 . . . . divide by the coefficient of x

If you're paying attention, you see that the solution of this kind of equation has the appearance that the denominator variable and the left-side value are simply swapped:
Effectively, we have multiplied both sides of the equation on the left by x/0.22. There is a <em>property of equality</em> that lets us do that. There is no such thing as a property of equality that says "swap with denominator." You must always pay attention to what is allowed by the properties of equality.

Digits that go on forever are irrational if I remeber correctly.
