Answer :

To solve the division of the given fractions [tex]\(\frac{1}{36} \div \frac{18}{4}\)[/tex], follow these steps:

1. Understand the operation: Division of fractions is equivalent to multiplying by the reciprocal of the divisor.

2. Identify the fractions:
- First fraction: [tex]\(\frac{1}{36}\)[/tex]
- Second fraction: [tex]\(\frac{18}{4}\)[/tex]

3. Find the reciprocal of the second fraction:
- The reciprocal of [tex]\(\frac{18}{4}\)[/tex] is [tex]\(\frac{4}{18}\)[/tex].

4. Rewrite the original operation using multiplication by the reciprocal:
[tex]\[ \frac{1}{36} \div \frac{18}{4} = \frac{1}{36} \times \frac{4}{18} \][/tex]

5. Multiply the numerators:
[tex]\[ 1 \times 4 = 4 \][/tex]

6. Multiply the denominators:
[tex]\[ 36 \times 18 = 648 \][/tex]

7. Form the new fraction from the results of the multiplication:
[tex]\[ \frac{4}{648} \][/tex]

8. Simplify the fraction:
- Identify the greatest common divisor (GCD) of 4 and 648, which is 4.
- Divide both the numerator and the denominator by 4:
[tex]\[ \frac{4 \div 4}{648 \div 4} = \frac{1}{162} \][/tex]

9. Convert the simplified fraction to a decimal:
- Perform the division [tex]\( \frac{1}{162} \)[/tex] to get the decimal form.
- [tex]\(\frac{1}{162} \approx 0.006172839506172839\)[/tex].

Therefore, the result of [tex]\(\frac{1}{36} \div \frac{18}{4}\)[/tex] is approximately [tex]\(0.006172839506172839\)[/tex].
