-35减-56

To subtract -3/5 from -5/6, we can first find a common denominator for the two fractions. The least common multiple (LCM) of 5 and 6 is 30.

Converting -3/5 to have a denominator of 30:

(-3/5) * (6/6) = -18/30

Now we can rewrite the subtraction as:

-5/6 - (-18/30)

To subtract a negative fraction, we change it to addition:

-5/6 + 18/30

Next, we need to find a common denominator of 6 and 30, which is 30.

Converting -5/6 to have a denominator of 30:

(-5/6) * (5/5) = -25/30

Now we can rewrite the expression as:

-25/30 + 18/30

Combining the numerators:

(-25 + 18)/30 = -7/30

Therefore, -3/5 minus -5/6 is equal to -7/30
