Sagot :

Sure, let's solve the problem of dividing the fractions [tex]\(\frac{7}{9}\)[/tex] by [tex]\(\frac{8}{15}\)[/tex].

### Step 1: Reciprocal of the second fraction
To divide by a fraction, multiply by its reciprocal. So, we take the reciprocal of [tex]\(\frac{8}{15}\)[/tex], which is [tex]\(\frac{15}{8}\)[/tex].

### Step 2: Multiplication
Multiply the first fraction by the reciprocal of the second fraction:

[tex]\[ \frac{7}{9} \times \frac{15}{8} \][/tex]

To multiply these fractions, we multiply the numerators and the denominators:

[tex]\[ \text{Numerator} = 7 \times 15 = 105 \][/tex]
[tex]\[ \text{Denominator} = 9 \times 8 = 72 \][/tex]

So, we have:

[tex]\[ \frac{7}{9} \div \frac{8}{15} = \frac{105}{72} \][/tex]

### Step 3: Simplifying the fraction
To simplify [tex]\(\frac{105}{72}\)[/tex], we find the greatest common divisor (GCD) of 105 and 72.

The GCD of 105 and 72 is 3.

Now, we divide both the numerator and the denominator by their GCD:

[tex]\[ \frac{105 \div 3}{72 \div 3} = \frac{35}{24} \][/tex]

So, the simplified form of [tex]\(\frac{105}{72}\)[/tex] is [tex]\(\frac{35}{24}\)[/tex].

### Final Answer
Thus, the simplified form of [tex]\(\frac{7}{9} \div \frac{8}{15}\)[/tex] is:

[tex]\[ \frac{35}{24} \][/tex]
