What is a fraction whose numerator is larger than the denominator?
An improper fraction
A fraction with a negative numerator whose absolute value is greater than its positive denominator is a number less than negative one?
Yes.
What are two fractions whose products are 1?
Take ANY fraction as the first fraction. Make sure it is either a proper fraction, or written as an improper fraction. For example, 7/4. For the other fraction, simply exchange the numerator and the denominator; in this example, that would be 4/7.
Are square root numbers rational?
In general, not usually.The square root of an irrational number is always irrational.The square root of a rational number is usually irrational, but not always. You can tell by this test:If both the numerator and denominator of the number expressed as a simplified fraction are perfect square numbers (a number whose square root is a whole number), then the square root of the whole fraction will be rational.Example: Sqrt(4) =2 (the positive one). Sqrt(1) = 1. Both are perfect squares.So sqrt(1/4) = sqrt(1)/sqrt(4) = 1/2. Another one: sqrt(4/9) = 2/3.
What is the square root of -52?
