A ratio that has integers for both quantities and that cannot be reduced any further (using integers) is said to be in simplest form or lowest terms. Sometimes it is useful to write a ratio in the form 1∶x or x∶1, where x is not necessarily an integer, to enable comparisons of different ratios.
What is a ratio of two integers?
A rational number is a number that can be written as a ratio of two integers. A rational number is a number that can be written in the form pq, where p and q are integers and q ≠ 0.
What is Fibonacci golden ratio?
The golden ratio is about 1.618, and represented by the Greek letter phi. The golden ratio is best approximated by the famous “Fibonacci numbers.” Fibonacci numbers are a never-ending sequence starting with 0 and 1, and continuing by adding the previous two numbers.
Is Division A ratio?

In the context of mathematics, the colon and fraction format are preferred. When comparing more than two quantities, opt for the colon format.
Can a repeating decimal be written as a integer?

Is 1.5 a positive integer?
