Solve the following exercise:
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The problem gives us the fractions and . The denominator can be converted to (the denominator of the second fraction) by multiplying by 4.
Step 2: Convert to , since . Now both fractions have a denominator of 8.
Step 3: Perform the subtraction: .
Step 4: Simplify by dividing both numerator and denominator by 2: .
Therefore, the solution to the problem is .
Solve the following exercise:
\( \frac{8}{5}-\frac{4}{5}=\text{?} \)
Fractions don't work like regular numbers! The denominator tells you what size pieces you're working with. You can only subtract pieces of the same size, so you need a common denominator first.
Look for the Least Common Multiple (LCM) of both denominators. In this case, since 8 is a multiple of 2, we can use 8 as our common denominator!
Yes! Always check if your answer can be simplified. simplifies to by dividing both top and bottom by their greatest common factor of 2.
Lucky you! When denominators are already the same, just subtract the numerators directly and keep the same denominator. Then simplify if needed.
Absolutely! If you subtract equal fractions like , you get zero. This is perfectly normal in fraction subtraction.
