Find the quotient: [tex]\frac{7}{8} \div \frac{3}{8}[/tex]

A. [tex]\frac{21}{64}[/tex]

B. [tex]\frac{3}{7}[/tex]

C. [tex]2 \frac{1}{3}[/tex]

D. [tex]7 \frac{1}{3}[/tex]


Sagot :

To solve the problem of dividing [tex]\(\frac{7}{8}\)[/tex] by [tex]\(\frac{3}{8}\)[/tex], we follow these steps:

1. Understand Division of Fractions:
To divide fractions, you multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping its numerator and denominator.

2. Write Down the Problem:
[tex]\[ \frac{7}{8} \div \frac{3}{8} \][/tex]

3. Find the Reciprocal of the Second Fraction:
The reciprocal of [tex]\(\frac{3}{8}\)[/tex] is [tex]\(\frac{8}{3}\)[/tex].

4. Replace Division with Multiplication by the Reciprocal:
Now, we need to find:
[tex]\[ \frac{7}{8} \times \frac{8}{3} \][/tex]

5. Multiply the Numerators Together:
[tex]\[ 7 \times 8 = 56 \][/tex]

6. Multiply the Denominators Together:
[tex]\[ 8 \times 3 = 24 \][/tex]

7. Form the New Fraction:
The product of the numerators over the product of the denominators gives us:
[tex]\[ \frac{56}{24} \][/tex]

8. Simplify if Necessary:
To simplify [tex]\(\frac{56}{24}\)[/tex], divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 56 and 24 is 8.
[tex]\[ \frac{56 \div 8}{24 \div 8} = \frac{7}{3} \][/tex]

9. Convert the Improper Fraction to a Mixed Number:
[tex]\[ \frac{7}{3} = 2 \frac{1}{3} \][/tex]

Thus, the quotient of [tex]\(\frac{7}{8} \div \frac{3}{8}\)[/tex] is:
[tex]\[ 2 \frac{1}{3} \][/tex]

Hence, the correct answer from the given options is:
[tex]\[ 2 \frac{1}{3} \][/tex]
