Question

The ratio of adults to children on a train in 7:2. There are 245 adults on the train. Find the total number of people on the train?

Answer 1

315 people

Explanation:

Using the given ratio, we can figure out the number of children on the train by doing cross multiplication.

Let x = # of children on train.

7/2 = 245/x

7x = 490

x = 70 children

The total number of people = 70 + 245 = 315 people total
