1 to 2 ratio
What does 1 times 1 equal?
Why? 1 times 1 or, written another way, 1×1 is a simple multiplication problem which equals 1. One reason for the above answer of one (1) is that the arithmetic operation of multiplication can be thought of as the grouping of objects.
Why does 1+1 equal 2?
If the definition of natural numbers and the operation of addition are understood, then 1 + 1 can be solved easily. By definition, 1 + 1 would mean the first subsequent number after 1, or simply the next number, which is equal to 2. Hence, the mathematical relationship, 1 + 1 = 2, can be proved.
What is meant by ratio of 1?
It is the result of comparing the hazard function among exposed to the hazard function among non-exposed. As for the other measures of association, a hazard ratio of 1 means lack of association, a hazard ratio greater than 1 suggests an increased risk, and a hazard ratio below 1 suggests a smaller risk.

Introduction A ratio is a way of comparing two or more similar quantities. Ratios can be used to compare costs, weights, sizes and other quantities. For example, suppose we have a model boat which is 1 m long, whereas the actual boat is 25 m long. Then the ratio of the length of the model to the length of the actual boat is 1 to 25.

A ratio is a comparison of two quantities with the same unit. For example, if one house has a floor area of 2,000 ft 2, and a second house has a floor area of 3,000 ft, the ratio of the areas is 2,000 to 3,000, or 2 to 3, simplified. To prepare students for working with ratios in algebra, the class will review the meanings
