Alanine Aminotransferase (ALT) An alanine aminotransferase (ALT) test measures the amount of this enzyme in the blood. ALT is found mainly in the liver, but also in smaller amounts in the kidneys , heart, muscles, and pancreas . ALT was formerly called serum glutamic pyruvic transaminase (SGPT).
To multiply fractions, all you have to do is multiply the numerators and denominators and simplify the result. To divide fractions, you simply have to flip the numerator and denominator of one of the fractions, multiply the result by the other fraction, and simplify.
Just as we can multiply and divide fractions, we can multiply and divide rational expressions, or fractions that include polynomials. In fact, we use the same processes for multiplying and dividing rational expressions as we use for multiplying and dividing numeric fractions.
