Problem 26 Convert to fraction notation. ... [FREE SOLUTION] (2024)

Fraction notation is a way of representing numbers that are not whole. It consists of two parts: the numerator and the denominator. The numerator is the top number and represents how many parts we have. The denominator is the bottom number and indicates how many parts make up a whole. For instance, in the fraction \( \frac{7}{100} \), 7 is the numerator and 100 is the denominator. This means out of 100 equal parts, we have 7.

Understanding fractions is essential as they are used in various real-life situations such as cooking, measurements, and even managing finances. Mastering fraction notation can help simplify these tasks.

Mixed numbers combine a whole number with a fraction. For example, \( 5 \frac{7}{100} \) includes the whole number 5 and the fraction \( \frac{7}{100} \). Converting a mixed number to an improper fraction involves a few clear steps:

• First, identify the whole number and the fractional part of the mixed number.
• Second, multiply the whole number by the denominator of the fraction.
• Then, add the numerator of the fraction to this product.

All of these are then placed over the original denominator. For instance, with \( 5 \frac{7}{100} \):
\( 5 \times 100 = 500 \) and adding the numerator gives us:
\( 500 + 7 = 507 \).
So, \( 5 \frac{7}{100} \) converts to \( \frac{507}{100} \). This conversion helps in performing easier mathematical operations and in comparing sizes.

An improper fraction is a fraction where the numerator is greater than or equal to the denominator. This means the value is either equal to or greater than one. For example, \( \frac{507}{100} \) is an improper fraction because 507 is larger than 100.

Improper fractions are useful in mathematics because they can simplify addition, subtraction, multiplication, and division. They can be converted back to mixed numbers to easily understand their value relative to 1. For example, \( \frac{507}{100} \) can be converted back to \( 5 \frac{7}{100} \). This makes it clear that we have a little more than 5 whole parts.

Mastery of improper fractions helps enhance problem-solving skills and makes complex mathematical equations more manageable.
