**2 - -3**

**3 5**

**This is equal to:**

3 5

**Find the Lowest common Denominator (LCD) of 3 and 5**

**15**.

**Rewrite the equivalent fractions with the new denominator of 15**

2 + 3

3 5

3 5

1. **Find the Lowest common Denominator (LCD) of 3 and 5 **

i.e find the smallest number that can be divided by both 3 and 5.

LCD of 3, and 5 is **15**.

2. **Rewrite the equivalent fractions with the new denominator of 15**

Remember whatever is done to the denominator of each fraction

must be done to its numerator also.

2(5) + 3(3) = 10 + 9

3(5) 5(3) 15 15

3. **Add the fractions**

Since their denominators are the same, simply add the numerators.

Remember that your final answer must be in its simplest form.

Hi Shakur,

Hope this helps!

The most important thing to remember is that two minuses are the same as a plus. So in this case we have 2/3 + 3/5.

Next, find the common denominator, which is 15 here. So:

2/3*5/5 = 10/15

and

3/5 * 3/3 = 9/15

Now you have 10/15 + 9/15, which will give you your answer.

2/3 - (-3/5)

First, let's get rid of the double negative: subtracting a negative is the same as adding a positive, so we could also write the expression as:

2/3 + 3/5

Now, to be able to add fractions, we need to come up with a common denominator. In this case, 15 would be the best option, so let's multiply each fraction to make them each have a denominator of 15.

2/3 x 5/5 = 10/15

3/5 x 3/3 = 9/15

So, 10/15 + 9/15 = 19/15, or 1 4/15
