Find the difference:
`9/(10)-3/(5)`

Answer

To find the difference between \( \frac{9}{10} \) and \( \frac{3}{5} \), we can follow these steps:

### Step 1: Identify the fractions
We have two fractions:
- \( \frac{9}{10} \)
- \( \frac{3}{5} \)

### Step 2: Find the Least Common Multiple (LCM)
To subtract these fractions, we need a common denominator. The denominators are 10 and 5.

The LCM of 10 and 5 is 10.

### Step 3: Convert the fractions to have the same denominator
- The first fraction \( \frac{9}{10} \) already has the denominator of 10.
- For the second fraction \( \frac{3}{5} \), we need to convert it to have a denominator of 10.

To do this, we multiply both the numerator and the denominator of \( \frac{3}{5} \) by 2:
\[ \frac{3}{5} = \frac{3 \times 2}{5 \times 2} = \frac{6}{10} \]

### Step 4: Subtract the fractions
Now we can subtract the two fractions:
\[ \frac{9}{10} - \frac{6}{10} = \frac{9 - 6}{10} = \frac{3}{10} \]

### Step 5: Write the final answer
The difference \( \frac{9}{10} - \frac{3}{5} \) is:
\[ \frac{3}{10} \]
