Divide to find the quotient of 7/8÷4 1/5

. Simplify the answer, if possible.(1 point)

1 answer

To divide the fraction \( \frac{7}{8} \) by the mixed number \( 4 \frac{1}{5} \), we first need to convert the mixed number into an improper fraction.

  1. Convert \( 4 \frac{1}{5} \) to an improper fraction:

    \[ 4 \frac{1}{5} = 4 \times 5 + 1 = 20 + 1 = 21 \]

    So, \( 4 \frac{1}{5} = \frac{21}{5} \).

  2. Now we can rewrite the division as follows:

    \[ \frac{7}{8} \div \frac{21}{5} \]

    Division by a fraction is the same as multiplying by its reciprocal:

    \[ \frac{7}{8} \times \frac{5}{21} \]

  3. Now, multiply the fractions:

    \[ \frac{7 \times 5}{8 \times 21} = \frac{35}{168} \]

  4. Next, we simplify \( \frac{35}{168} \). To do this, we can find the greatest common divisor (GCD) of 35 and 168.

    • The factors of 35 are \( 1, 5, 7, 35 \)
    • The factors of 168 are \( 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 28, 42, 84, 168 \)

    The common factor is 7.

  5. Now, divide both the numerator and denominator by their GCD, 7:

    \[ \frac{35 \div 7}{168 \div 7} = \frac{5}{24} \]

So, the final simplified quotient of \( \frac{7}{8} \div 4 \frac{1}{5} \) is

\[ \frac{5}{24} \]
