Front

What is the definition of a Rational Number?

Back

A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

Front

What does LCM stand for?

Back

LCM stands for Least Common Multiple, which is the smallest multiple that is exactly divisible by two or more numbers.

Front

What is the formula to find the LCM of two numbers?

Back

The LCM of two numbers can be found using the formula: LCM(a, b) = (a * b) / GCF(a, b).

Front

What is the definition of GCF?

Back

GCF stands for Greatest Common Factor, which is the largest positive integer that divides two or more numbers without leaving a remainder.

Front

How do you find the GCF of two numbers?

Back

To find the GCF, list the factors of each number and identify the largest factor they have in common.

Front

What is the relationship between LCM and GCF?

Back

The relationship is given by the formula: LCM(a, b) * GCF(a, b) = a * b.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction.

Front

How do you compare absolute values of two numbers?

Back

To compare absolute values, find the absolute value of each number and then compare the results.

Back

The LCM of 15 and 2 is 30.

Front

What is the GCF of 12 and 16?

Back
