To convert the fraction \( \frac{29}{100} \) to a decimal using long division, we divide 29 by 100.
- Start with 29. Since 100 is larger than 29, we will need to add a decimal point and zeros.
- Write it as 29.000 (adding zeros to assist in the division).
- Now divide 100 into 290 (the first three digits including the decimal point).
- 100 goes into 290 two times (because \( 2 \times 100 = 200 \)).
- Subtract 200 from 290, which leaves us with 90.
- Bring down the next zero, making it 900.
- Now divide 100 into 900. It fits 9 times (since \( 9 \times 100 = 900 \)).
- Subtract 900 from 900, which leaves us with 0.
So, \( 29 \div 100 = 0.29 \).
Now, rounding 0.29 to one decimal place, we get 0.3.
Therefore, the decimal approximation of \( \frac{29}{100} \) to one decimal place is 0.3.
