Zorluk: ZorFraction Operations

Arrange the following fractions and mixed numbers in ascending order (from least to greatest).

  1. 127122 \frac{7}{12}
  2. 22582 \frac{5}{8}
  3. 383\frac{8}{3}
  4. 4114\frac{11}{4}

Cevap

The correct ascending order is 27122 \frac{7}{12}, 2582 \frac{5}{8}, 83\frac{8}{3}, and 114\frac{11}{4}.
By converting all values to mixed numbers with a common denominator of 24, we find their fractional parts are 1424\frac{14}{24}, 1524\frac{15}{24}, 1624\frac{16}{24}, and 1824\frac{18}{24}. Because all whole numbers are 2, the order of the original fractions matches the ascending order of these fractional parts.

Adım Adım Çözüm

1
Convert the improper fractions to mixed numbers to simplify comparison.
114=234\frac{11}{4} = 2 \frac{3}{4} and 83=223\frac{8}{3} = 2 \frac{2}{3}. The other numbers are already mixed numbers: 2582 \frac{5}{8} and 27122 \frac{7}{12}.
Because all the whole numbers are 2, we only need to compare their fractional parts to determine the order.
2
Identify the least common denominator (LCD) for the fractional parts: 34\frac{3}{4}, 58\frac{5}{8}, 712\frac{7}{12}, and 23\frac{2}{3}.
The denominators are 4, 8, 12, and 3. The lowest number they all divide into evenly is 24.
A common denominator is required to accurately compare the sizes of fractions with unlike denominators.
3
Convert each fractional part to an equivalent fraction with a denominator of 24.
34=1824\frac{3}{4} = \frac{18}{24}, 58=1524\frac{5}{8} = \frac{15}{24}, 712=1424\frac{7}{12} = \frac{14}{24}, and 23=1624\frac{2}{3} = \frac{16}{24}.
Multiplying both the numerator and denominator by the same value preserves the fraction's overall mathematical value.
4
Order the converted fractions from least to greatest based on their numerators.
1424<1524<1624<1824\frac{14}{24} < \frac{15}{24} < \frac{16}{24} < \frac{18}{24}.
When denominators are equal, a larger numerator represents a larger overall value.
5
Match the ordered fractions back to their original given forms.
27122 \frac{7}{12} (from 1424\frac{14}{24}), 2582 \frac{5}{8} (from 1524\frac{15}{24}), 83\frac{8}{3} (from 1624\frac{16}{24}), and 114\frac{11}{4} (from 1824\frac{18}{24}).
The final answer must present the exact numbers provided in the original stem.
