Solve the following exercise:
To solve the problem, we'll follow these steps:
Now, let's calculate:
Step 1: Both fractions and have a common denominator of 5.
Step 2: Subtract the numerators:
.
Step 3: Place the result over the common denominator:
.
Therefore, the solution to the problem is .
Solve the following exercise:
\( \frac{8}{5}-\frac{4}{5}=\text{?} \)
When fractions have the same denominator, you're working with the same-sized pieces! Think of it like pizza slices - if you have 8 fifths and take away 4 fifths, you still have fifths, just fewer of them.
Then you'd need to find a common denominator first! But here both fractions already have 5 as the denominator, so we can subtract directly.
Add your answer back to the second fraction: . If you get the first fraction, you're right!
You could, but it's often easier to work with fractions directly. Plus, is the exact answer while 0.8 is just an approximation.
That's called an improper fraction and it's perfectly valid! You can convert it to a mixed number if needed, but improper fractions are often easier to work with.
