Question

Simplify 8/63-(-5/21)​

Answer 1

`(23)/(63)`

Explanation:

To simplify this, let's first write it out in an easier way:

`(8)/(63) - (-5)/(21)`

Next, we have to simplify, and the first step is to find a common denominator between the 2.

The common denominator is 63, so we have to multiply the 2nd fraction by 3.

`(8)/(63) - (-15)/(63)\\`

Next, we have a "-" followed by a "-", which will cancel each other out to form a +"

`(8)/(63) + (15)/(63)\\`

Now add the numerators and keep the denominators the same:

`(23)/(63)`

Hope this helps! :)

Answer 2

23/63

Explanation:

To simplify the expression 8/63 - (-5/21), we can follow these steps:

Step 1: Simplify the double negative by changing the sign of the second fraction.

8/63 + 5/21

Step 2: Find a common denominator for the fractions, which in this case is 63.

To convert the second fraction, multiply the numerator and denominator by 3.

8/63 + (5 * 3)/(21 * 3)

=8/63 + 15/63

Step 3: Combine the fractions with the common denominator.

(8 + 15)/63

=23/63

Therefore, the simplified expression is 23/63.
