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.
