Answer:
7/10
Step-by-step explanation:
Step 1
We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator.
Now we multiply 1 by 5, and get 5, then we multiply 2 by 5 and get 10.
1/2 times 5
Now for the second term. You multiply 1 by 2, and get 2, then multiply 2 by 5 and get 10.
1/5 times 2
This gives us a new problem that looks like so:
5
10
+
2
10
Step 2
Since our denominators match, we can add the numerators.
5 + 2 = 7
That gives us an answer of
7
10
Step 3
Can this fraction be reduced?
First, we attempt to divide it by 2...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
Nope! So now we try the next greatest prime number, 11...
No good. 11 is larger than 7. So we're done reducing.
There you have it! Here's the final answer to 1/2 + 1/5
