Let's solve the problem of
converting decimals to fractions step by step.
We'll go through each decimal and convert it into a fraction in its simplest form.

🔹 General Rule:
To convert a decimal to a fraction:
1. Write the decimal as a fraction with the denominator being a power of 10 (based on the number of decimal places).
2. Simplify the fraction by dividing numerator and denominator by their greatest common divisor (GCD).

✔ Solutions:
#### 1) 0.1
= $ \frac{1}{10} $
(Simplest form)
#### 2) 0.02
= $ \frac{2}{100} = \frac{1}{50} $
(Simplify by dividing numerator and denominator by 2)
#### 3) 0.003
= $ \frac{3}{1000} $
(Already simplified)
#### 4) 0.123
= $ \frac{123}{1000} $
(No common factors; already simplified)
#### 5) 0.4
= $ \frac{4}{10} = \frac{2}{5} $
(Simplify by dividing by 2)
#### 6) 0.05
= $ \frac{5}{100} = \frac{1}{20} $
(Simplify by dividing by 5)
#### 7) 0.006
= $ \frac{6}{1000} = \frac{3}{500} $
(Simplify by dividing by 2)
#### 8) 0.456
= $ \frac{456}{1000} $
Simplify: GCD of 456 and 1000 is 8
$ \frac{456 ÷ 8}{1000 ÷ 8} = \frac{57}{125} $
#### 9) 0.4056
= $ \frac{4056}{10000} $
Find GCD of 4056 and 10000 → GCD = 8
$ \frac{4056 ÷ 8}{10000 ÷ 8} = \frac{507}{1250} $
#### 10) 0.0456
= $ \frac{456}{10000} $
Same as above: GCD = 8
$ \frac{456 ÷ 8}{10000 ÷ 8} = \frac{57}{1250} $

#### 11) 0.5
= $ \frac{5}{10} = \frac{1}{2} $
#### 12) 0.50
= $ \frac{50}{100} = \frac{1}{2} $
(Note: 0.50 = 0.5, so same as above)
#### 13) 0.500
= $ \frac{500}{1000} = \frac{1}{2} $
(Same value, just more zeros)
#### 14) 0.7
= $ \frac{7}{10} $
#### 15) 0.70
= $ \frac{70}{100} = \frac{7}{10} $
#### 16) 0.700
= $ \frac{700}{1000} = \frac{7}{10} $
#### 17) 0.06
= $ \frac{6}{100} = \frac{3}{50} $
#### 18) 0.060
= $ \frac{60}{1000} = \frac{6}{100} = \frac{3}{50} $
(Trailing zero doesn’t change value)
#### 19) 0.0600
= $ \frac{600}{10000} = \frac{6}{100} = \frac{3}{50} $
#### 20) 0.76
= $ \frac{76}{100} = \frac{19}{25} $
(Simplify by dividing by 4)

📝 Notes:
- Trailing zeros do
not change the value of a decimal.
- Always simplify fractions to lowest terms.
- For decimals with many digits, use prime factorization or a calculator to find GCD.
