Question

13/20+5/8
Can someone help me with this in steps?

Answer 1

First thing you need to do, in order to add straight across like this:

`(13)/(20) + (5)/(8)`
You need to set the denominators equal to each other, by finding out the greatest common multiple. Which in this case is 40.


`(2 * 13)/(2 * 20) + (5 * 5)/(5 * 8)`
When you multiply, whatever you do to the denominators you must do the same to the numerator. Our new fractions should now have equal denominators like below:

`(26)/(40) + (25)/(40)`
Now keeping the same denominators you can simply add together 26 and 25

`26 + 25 = 41`

`(41)/(40)`
Now you need to simply this improper fraction, to get the final answer.

ANSWER:

`1 (1)/(40)`
