Answer 2

Let's solve each of these step by step:

1. $\frac{3}{5} + \frac{1}{4}$

To add these fractions, you need a common denominator. In this case, the common denominator is 20. So:

$\frac{3}{5} + \frac{1}{4} = \frac{12}{20} + \frac{5}{20} = \frac{17}{20}$

2. $\frac{3}{25} + \frac{19}{40}$

To add these fractions, you need a common denominator. The common denominator is 200. So:

$\frac{3}{25} + \frac{19}{40} = \frac{24}{200} + \frac{95}{200} = \frac{119}{200}$

3. $\frac{103}{125} - \frac{1}{4}$

To subtract these fractions, you need a common denominator. The common denominator is 500. So:

$\frac{103}{125} - \frac{1}{4} = \frac{412}{500} - \frac{125}{500} = \frac{287}{500}$

4. $10 \frac{1}{4} - 6 \frac{1}{5}$

First, convert the mixed numbers to improper fractions:

$10 \frac{1}{4} = \frac{41}{4}$ $6 \frac{1}{5} = \frac{31}{5}$

Now, subtract:

$\frac{41}{4} - \frac{31}{5}$

To subtract these fractions, you need a common denominator. The common denominator is 20. So:

$\frac{205}{20} - \frac{124}{20} = \frac{81}{20}$

So, the results are:

1. $\frac{3}{5} + \frac{1}{4} = \frac{17}{20}$
2. $\frac{3}{25} + \frac{19}{40} = \frac{119}{200}$
3. $\frac{103}{125} - \frac{1}{4} = \frac{287}{500}$
4. $10 \frac{1}{4} - 6 \frac{1}{5} = \frac{81}{20}$
