9/11z_4/11z
To simplify this expression, we need to find a common denominator for the fractions 9/11z and 4/11z. The common denominator is 11z because both fractions have a denominator of 11z.
Next, we can rewrite the expression using the common denominator:
(9/11z) - (4/11z)
Now, we can subtract the fractions:
(9 - 4)/(11z)
Simplifying the numerator, we get:
5/(11z)
To simplify the expression (9/11z) - (4/11z), you can follow these steps:
Step 1: Find a common denominator for the fractions 9/11z and 4/11z. In this case, the common denominator is 11z.
Step 2: Rewrite both fractions with the common denominator.
For the first fraction, multiply both numerator and denominator by z to get: (9z)/(11z).
For the second fraction, no changes are needed since the denominator is already 11z: 4/(11z).
Step 3: Subtract the two fractions.
(9z)/(11z) - 4/(11z) = (9z - 4)/(11z).
Therefore, the simplified expression is (9z - 4)/(11z).
To simplify the expression 9/11z - 4/11z, you need to combine the two fractions with the same denominator.
Step 1: Find the common denominator.
In this case, the common denominator is 11z since both fractions have the same denominator, 11z.
Step 2: Rewrite the fractions with the common denominator.
9/11z becomes (9 * z)/(11 * z) = 9z/11z
4/11z remains as it is.
Step 3: Subtract the fractions.
Now that both fractions have the same denominator, you can directly subtract the numerators while keeping the denominator the same.
(9z - 4) / 11z
So, the simplified expression is (9z - 4) / 11z.
