-2/3 - 5/6
We need common denominators so, since 3 can go into 6, we only need to multiply the first fraction by 2.
= -2 x 2 / 3x2 - 5/6
= -4 / 6 - 5/6
We only subtract the numbers that are in the numerators,
= -4-5 / 6
= -9/6
Both nine and six are divisible by 3, so to put into lowest terms...
=-9÷3 / 6÷3
= -3/2 <--- Final Answer
