Question

9/11 - 1/2 in it's simplest form​

Answer 1

7/22

Explanation:

Step 1: Define/explain.

To subtract fractions with different denominators, you must first find the least common denominator (LCM).

You can do this by listing the multiples of each denominator.

Step 2: Solve.

11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110

2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22

22 is the LCM.

Now, we change the fractions to where they both have denominators of 22.

**REMEMBER: WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MULTIPLY IT BY THE NUMERATOR AS WELL!!**

`9/11*2/2=18/22`

`1/2*11/11=11/22`

Now, subtract as normal.

`18/22-11/22=7/22`

`7/22 (simplified).`

Step 3: Conclude.

Therefore, 9/11 - 1/2 = 7/22.
