What is 9/32 + 8/9?

What is 9/32 + 8/9?

This is how you add

9
32
+
8
9

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 9 by 9, and get 81, then we multiply 32 by 9 and get 288.

9/32 times 9

Do the same for the second term. We multiply 8 by 32, and get 256, then multiply 32 by 9 and get 288.

8/9 times 32

The problem now has new fractions to add:

81
288
+
256
288

Step 2

Since our denominators match, we can add the numerators.

81 + 256 = 337

This yields the answer

337
288

Step 3

The last step is to reduce the fraction if we can.

To find out, we try dividing it by 2...

No good. 293 is larger than 288. So we're done reducing.
