  • Use a calculator: Use a calculator to find the GCD of two numbers.

Q: What is the difference between a fraction and a decimal?

A: A fraction is a way of expressing a part of a whole, while a decimal is a way of expressing a number as a sum of powers of 10. For example, the fraction 12\frac{1}{2} is equal to the decimal 0.5.

Q: How do I convert a fraction to a decimal?

A: To convert a fraction to a decimal, you can divide the numerator by the denominator. For example, to convert the fraction 12\frac{1}{2} to a decimal, you can divide 1 by 2, which equals 0.5.

Q: What is the difference between a proper fraction and an improper fraction?

A: A proper fraction is a fraction where the numerator is less than the denominator, while an improper fraction is a fraction where the numerator is greater than or equal to the denominator. For example, the fraction 12\frac{1}{2} is a proper fraction, while the fraction 32\frac{3}{2} is an improper fraction.

Q: How do I simplify a fraction?
