What is 87/100 + 1/11?

What is 87/100 + 1/11?

This is how we add

87
100
+
1
11

Step 1

Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.

So, we multiply 87 by 11, and get 957, then we multiply 100 by 11 and get 1100.

87/100 times 11

Now for the second term. You multiply 1 by 100, and get 100, then multiply 100 by 11 and get 1100.

1/11 times 100

We now have a new problem, that looks like this:

957
1100
+
100
1100

Step 2

Since our denominators match, we can add the numerators.

957 + 100 = 1057

That gives us the sum, which is

1057
1100

Step 3

Now, do we need to simplify this fraction?

First, we attempt to divide it by 2...
