Use long division to convert 12/30 to a decimal A4 B 12.3 C 0.4 D 2.5

Answer 1

To convert \( \frac{12}{30} \) to a decimal using long division, we will divide 12 by 30.

1. Set up the long division with 12 inside the division bracket and 30 outside.

2. Since 12 is less than 30, we write 0 and add a decimal point.

3. We will add a zero to 12 to make it 120.

4. Now, see how many times 30 goes into 120:

   • \( 30 \times 4 = 120 \)

5. So, we write down 4 after the decimal point.

6. Subtract \( 120 - 120 = 0 \).

Now, we have:

\[ 12 \div 30 = 0.4 \]

Thus, \( \frac{12}{30} = 0.4 \).

The answer is C: 0.4.
