Step-by-step explanation:
Step 1
Of course, you can't add two fractions if the denominators (bottom numbers) don't match. To get a common denominator, multiply the denominators together. Then we fix the numerators by multiplying each one by their other term's denominator.
Now you multiply 2 by 9, and get 18, then we multiply 7 by 9 and get 63.
2/7 times 9
Do the same for the second term. We multiply 4 by 7, and get 28, then multiply 7 by 9 and get 63.
4/9 times 7
The problem now has new fractions to add:
18
63
+
28
63
Step 2
Since our denominators match, we can add the numerators.
18 + 28 = 46
The sum we get is
46
63
Step 3
The last step is to reduce the fraction if we can
To find out, we try dividing it by 2.

No good. 47 is larger than 46. So we're done reducing.
