-8over4,subtract7over6
I'm going to assume your problem is this:
-8/4 - 7/6 = ?
-8/4 is the same as -2.
Let's convert -2 to a fraction using 6 as the denominator:
-12/6 - 7/6 = -19/6
I hope this helps and is what you were asking.
To evaluate the expression -8/4 - 7/6, we can follow these steps:
Step 1: Simplify the fractions, if necessary.
- The fraction -8/4 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4. This gives us -2/1 or simply -2.
- The fraction 7/6 is already in its simplest form.
Step 2: Find a common denominator for the fractions.
- In this case, the fractions have different denominators. To find a common denominator, we need to find the least common multiple (LCM) of 4 and 6, which is 12.
Step 3: Rewrite the fractions with the common denominator.
- For -2, we can rewrite it as -2/1 or -24/12 (multiplying numerator and denominator by 12).
- For 7/6, we can rewrite it as 14/12 (multiplying numerator and denominator by 2).
Step 4: Perform the subtraction.
- Now that both fractions have the same denominator, we can subtract them:
-24/12 - 14/12 = (-24 - 14)/12 = -38/12.
Step 5: Simplify the resulting fraction, if necessary.
- The fraction -38/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2. This yields -19/6 as the final answer.
So, -8/4 - 7/6 evaluates to -19/6.
