Complete the following exercise:
To solve this problem, let's follow these steps:
Step 1: We have the fraction and we want to divide it by 3. We will convert this division into multiplication by the reciprocal of 3, which is . Thus, the operation becomes:
Step 2: Perform the multiplication. Multiply the numerators together and the denominators together:
Numerator:
Denominator:
This results in the fraction .
Step 3: Simplify . Notice that the numerator and the denominator have a common factor of 3:
Divide both the numerator and the denominator by 3:
Therefore, the solution to the problem is .
Solve the following exercise:
\( \frac{1}{4}:\frac{1}{2}=\text{?} \)
Dividing by a whole number is the same as multiplying by its reciprocal! This method works for all division problems with fractions and gives you a clear step-by-step process.
The reciprocal of any whole number is 1 divided by that number. So the reciprocal of 3 is , reciprocal of 5 is , and so on.
Yes! Always check if your final fraction can be simplified. Look for common factors in the numerator and denominator, like how simplifies to because both 3 and 27 are divisible by 3.
Find the greatest common factor (GCF) of the numerator and denominator. If the GCF is greater than 1, you can simplify! For , the GCF is 3, so divide both parts by 3.
For this type of problem, you'll typically get a proper fraction (numerator smaller than denominator) since you're dividing a fraction by a whole number, making it even smaller.
