To convert \( \frac{27}{50} \) to a decimal using long division, we divide 27 by 50.
-
Set up the long division: Since 27 is less than 50, we know the result will be less than 1. We can express this as \( 0.54 \) (by adding a decimal and zeros to the dividend).
-
Divide:
- 50 goes into 270 (27.0) five times because \( 50 \times 5 = 250 \).
- Subtract 250 from 270: \( 270 - 250 = 20 \).
- Bring down the next 0 to make it 200.
-
Continue dividing:
- 50 goes into 200 four times because \( 50 \times 4 = 200 \).
- Subtract 200 from 200: \( 200 - 200 = 0 \).
Since there are no more digits to bring down and the remainder is 0, we can conclude that:
\[ \frac{27}{50} = 0.54 \]
Thus, the answer is \( 0.54 \).
