Zorluk: KolayHCF and LCM

What is the Highest Common Factor (HCF) of the fractions 815\frac{8}{15} and 1425\frac{14}{25}?

  1. 275\frac{2}{75}Cevap
  2. B
    565\frac{56}{5}
  3. C
    25\frac{2}{5}
  4. D
    5675\frac{56}{75}

Cevap

The Highest Common Factor (HCF) is 275\frac{2}{75}.
The correct answer is found by taking the Highest Common Factor (HCF) of the numerators (88 and 1414), which is 22, and dividing it by the Least Common Multiple (LCM) of the denominators (1515 and 2525), which is 7575. This yields exactly 275\frac{2}{75}.

Adım Adım Çözüm

1
Identify the numerators and denominators of the given fractions.
The numerators are 88 and 1414. The denominators are 1515 and 2525.
The formula for the HCF of fractions requires processing numerators and denominators separately.
2
Calculate the Highest Common Factor (HCF) of the numerators.
The HCF of 88 and 1414 is 22.
According to the formula, the numerator of the final answer must be the HCF of the original numerators.
3
Calculate the Least Common Multiple (LCM) of the denominators.
The LCM of 1515 and 2525 is 7575.
According to the formula, the denominator of the final answer must be the LCM of the original denominators.
4
Combine the results into a single fraction.
The resulting fraction is 275\frac{2}{75}.
The HCF of fractions is defined as HCF of numeratorsLCM of denominators\frac{\text{HCF of numerators}}{\text{LCM of denominators}}.
