What is 40/41 + 4/11?

What is 40/41 + 4/11?

Here's how you add

40
41
+
4
11

Step 1

We can't add two fractions with different denominators (the bottom number). So you need to get a common denominator - both bottom numbers need to match. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 40 by 11, and get 440, then we multiply 41 by 11 and get 451.

40/41 times 11

Do the same for the second term. We multiply 4 by 41, and get 164, then multiply 41 by 11 and get 451.

4/11 times 41

So now our fractions look like this:

440
451
+
164
451

Step 2

Since our denominators match, we can add the numerators.

440 + 164 = 604

So the answer is:

604
451

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

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

No good. 457 is larger than 451. So we're done reducing.
