why 5/6 is greater than 5/7

Answer: 56>57\frac{5}{6} > \frac{5}{7} because both fractions have the same numerator, and dividing a whole into 6 equal parts yields larger individual parts than dividing it into 7 equal parts (5×16>5×175 \times \frac{1}{6} > 5 \times \frac{1}{7}). Equivalently, with common denominators, 3542>3042\frac{35}{42} > \frac{30}{42}.

Step-by-step solution

Step 1: Analyze the Numerators and Denominators

Both fractions have the same numerator, which is 55. A fraction ab\frac{a}{b} represents taking aa parts out of an object divided into bb equal parts.

Step 2: Understand the Meaning of the Denominator

The denominator tells us how many equal parts the whole is divided into. Dividing a whole into fewer parts makes each part larger, so each 16\frac{1}{6} piece is larger than each 17\frac{1}{7} piece.

Step 3: Compare the Same Number of Parts

Since each 16\frac{1}{6} part is larger than each 17\frac{1}{7} part, taking 55 of the larger parts will always give a greater total than taking 55 of the smaller parts. For fractions with the same numerator, the fraction with the smaller denominator is always greater.

Step 4: Verify Using a Common Denominator

To confirm arithmetically, we convert both fractions to like fractions using their common denominator, 4242. Comparing the numerators, since 35>3035 > 30, it confirms that 3542>3042\frac{35}{42} > \frac{30}{42}, so 56>57\frac{5}{6} > \frac{5}{7}.
