Final answer:
To divide 12 by 5, you place 5 outside the division bracket and 12 inside, divide 12 by 5 getting a quotient of 2 with a remainder of 2, then bring down a zero giving 20, which divided by 5 equals 4. The final answer is 2.4.
Step-by-step explanation:
To divide 12 by 5, we can set it up as a simple division problem where 12 is the dividend and 5 is the divisor.
Here is a step-by-step breakdown:
- Place the divisor (5) outside the division bracket and the dividend (12) inside the bracket.
- See how many times 5 goes into 12 without going over. In this case, it is 2 times because 5 x 2 = 10.
- Write down 2 as part of the quotient above the division bracket.
- Subtract 10 (5 x 2) from 12 to get a remainder of 2.
- Since 5 does not fit into 2, we need to add a decimal place to the quotient and bring down a zero to make the number 20.
- Now divide 20 by 5, which equals 4. This 4 goes after the decimal in our quotient.
- This gives us a final answer of 2.4 with no remainder.
Therefore, the correct answer is b) 2.4.
