A country exported 60,000,000 less than it imported, creating a negative balance

...and the question is?

We know imports > exports. Therefore we have a trade imbalance of 60,000,000. On the fiscal budget for the country this would be recorded in red or with a - sign or these signs <>.

wath is a ratio

In arithmetic a ratio is when we divide one number by another to see how they compare.

Thus if we wanted to know the ratio of 10 to 12 we'd have 10/12 = 5/6

With numbers a ratio is always expressed as a fraction or decimal.

If two quantities are in whole number multiples, then we use integers. If there are 20 people in a group and 5 own a pet, then the ratio of non-pet-owners to pet-owners is 15:5 or 3 to 1.

In geometry ratio has another meaning. We use the term in comparing the parts/properties of triangles. We speak of the ratio of perimeters, areas, angles and sides.
