Answer:
-7/8
Step-by-step explanation:
First, find the lowest common multiple of both 8 and 6.
Multiples of 6: 6, 12, 18, 24
Multiples of 8: 8, 16, 24
The LCM of 6 and 8 is 24.
Now multiply both the numerator and denominator of both fractions so that both denominators equal 24.
-3/6
Take both the numerator and denominator and multiply them by 4.
-12/24.
-3/8
Take both the numerator and denominator and multiply them by 3.
-9/24.
Now we have two fractions, -12/24 and -9/24.
The question tells us to add these fractions, so add the numerators and get
(-12) + (-9) = -21.
Finally, simplify the final fraction.
-21/24
Divide both the numerator and denominator by 3.
-7/8
Your answer is B. -7/8.
