Answer 2

Fractions:

The given fractions are: - Two-thirds (2/3) - Eleven-twelfths (11/12) - Seven-fifths (7/5) - One-hundredth (1/100) - Fifteen-sixths (15/6) - Eight-sevenths (8/7) - Twenty-three-hundredths (23/100) - Nine-ninths (9/9)

To determine which of these fractions are proper (also known as "right") and which are improper (also known as "wrong"), we need to compare the numerator (top number) and the denominator (bottom number) of each fraction.

A proper fraction is one where the numerator is less than the denominator, while an improper fraction is one where the numerator is equal to or greater than the denominator.

Based on this definition, the following fractions are proper: - Two-thirds (2/3) - Eleven-twelfths (11/12) - Seven-fifths (7/5) - One-hundredth (1/100) - Fifteen-sixths (15/6) - Eight-sevenths (8/7) - Twenty-three-hundredths (23/100) - Nine-ninths (9/9)

None of the given fractions are improper.

Fractions with Denominator 7:

To find all the fractions with a denominator of 7, we need to check which fractions have a denominator of 7.

Among the given fractions, none have a denominator of 7.

Fractions with Numerator 5:

To find all the fractions with a numerator of 5, we need to check which fractions have a numerator of 5.

Among the given fractions, none have a numerator of 5.

Fraction with Numerator 5 Units Less than Denominator:

To find the fraction where the numerator is 5 units less than the denominator, we can subtract 5 from the denominator.

The fraction with a numerator 5 units less than the denominator is 4/9. (9 - 5 = 4)

Fraction with Denominator 3 Times Greater than Numerator:

To find the fraction where the denominator is 3 times greater than the numerator, we can multiply the numerator by 3.

The fraction with a denominator 3 times greater than the numerator is 3/1. (1 * 3 = 3)
