Are ratios always rational?
No, but the reverse is true. All rational numbers are ratios but not all ratios are rational. You will often come across π being defined as the RATIO of the circumference of a circle to its diameter (there are other definitions). However, the word "rational" is derived from "ratio".
What is a ratio of integers?
The ratio of integers to rational numbers is 0.
Numbers that can be written as the ratio of two integers are called what numbers?
Rational
What is the meaning positive rational numbers?
Any number that can be expressed as the ratio x/y where x and y are both positive integers. [Technically, they could both be negative, but not one of each.]
Is 2247000 rational or irrational?

Is the ratio of two natural numbers always positive?
No, the ratio of two natural numbers can be positive, negative, or zero depending on the numbers being divided.
Which set is the intersection of integers and rational numbers?
The intersection of integers and rational numbers is the set of integers. Integers are whole numbers that can be positive, negative, or zero, while rational numbers are numbers that can be expressed as a ratio of two integers. Since all integers can be expressed as a ratio of the integer itself and 1, they are a subset of rational numbers, making their intersection the set of integers.
Is negative 15 rational?

Is the number 88 a rational number?
Yes, the number 88 is rational. A "rational number" is any number that can be expressed as a ratio of integers. That is A/B where A and B are integers, and not zero. Rational numbers include all positive and negative integers and all positive and negative fractions (and mixed numbers when expressed as a fraction).
Is - 14 a rational number?
Yes. It's the ratio of 14/1, 28/2, etc.
Are rational numbers counting numbers?
