5/10 + 5/20 = ? show some work . this is 20 points (i paid 40 points) just to get the answer.

5/10 + 5/20 = ?

First thing to do is, find the LCM.

10,20
20

So 20 is the LCM.

So ?/20 + ?/20

Now, divide the 20 to the denominator 10. = 2.
Now, Multiply the 2 and 5 = 10

So, 10/20 + ?/20

Then for the second one, do it the same as the first one. If you still dunno how, lemme answer this.

Now, Divide the 20(LCM) to the 20(DENOMINATOR OF THE SECOND ONE) = 1
Now, Multiply the 1 and 5 = 5.

So its 10/20 + 5/20 =

15/20.

We see that it can be reduced into lowest terms.
15/20 ÷ 5 = ?

So, 3/4 is the answer.
