To solve the multiplication of an integer with a fraction, we need to follow these steps:
Now, let's work through each step:
Step 1: Multiply 7 by 6, which gives us as the numerator.
Step 2: The denominator remains 8, so we have the fraction .
Step 3: Simplify by finding the greatest common divisor (GCD) of 42 and 8. The GCD is 2.
We divide the numerator and the denominator by 2: .
Step 4: Convert into a mixed number:
Divide 21 by 4, which equals 5 with a remainder of 1. Thus, is equivalent to the mixed number .
Therefore, the solution to the problem is .
\( 5:\frac{2}{5}= \)
When multiplying a fraction by a whole number, you're finding 7 groups of . Think of it as . The denominator stays the same!
Convert to a mixed number when the numerator is larger than the denominator (improper fraction). Since 21 > 4, we write as .
Start by checking if both numbers are even (divisible by 2). For 42 and 8, both are even, so divide by 2. Keep dividing by common factors until you can't anymore.
Yes! and are equivalent. However, mixed numbers are often preferred because they're easier to visualize and compare.
You can simplify before or after multiplying! , so . Both methods give the same result.
