Divide 1 1/2 divided by 1/4 in simplest form
The Correct Answer and Explanation is :
To divide the mixed number (1 \frac{1}{2}) by the fraction (\frac{1}{4}), follow these steps:
Step 1: Convert the Mixed Number to an Improper Fraction
A mixed number consists of a whole number and a fractional part. To convert (1 \frac{1}{2}) to an improper fraction:
- Multiply the whole number (1) by the denominator (2):
[
1 \times 2 = 2
] - Add the numerator (1) to this product:
[
2 + 1 = 3
] - Place this result over the original denominator (2):
[
1 \frac{1}{2} = \frac{3}{2}
]
Step 2: Set Up the Division Problem
Now, we have the division problem:
[
\frac{3}{2} \div \frac{1}{4}
]
Step 3: Multiply by the Reciprocal
To divide by a fraction, multiply by its reciprocal. The reciprocal of (\frac{1}{4}) is (\frac{4}{1}). Therefore, we rewrite the division as multiplication:
[
\frac{3}{2} \times \frac{4}{1}
]
Step 4: Perform the Multiplication
Now, multiply the numerators and denominators:
[
\frac{3 \times 4}{2 \times 1} = \frac{12}{2}
]
Step 5: Simplify the Result
Now, simplify (\frac{12}{2}):
[
\frac{12}{2} = 6
]
Conclusion
The answer to (1 \frac{1}{2} \div \frac{1}{4}) is 6.
Explanation
When dividing fractions, converting mixed numbers into improper fractions is essential to simplify calculations. Multiplying by the reciprocal helps us perform the division seamlessly. This method is based on the principle that dividing by a number is equivalent to multiplying by its reciprocal. Here, the mixed number was first converted, then the operation transformed from division to multiplication, making it easier to arrive at the final result. The simplification step is crucial, as it ensures that the answer is expressed in its simplest form.
