Answer 3

Let's solve each of these addition problems step by step:

a) $\frac{3}{8} + 2\frac{1}{4}$

First, find a common denominator, which in this case is 8.

$\frac{3}{8} + \frac{2 \cdot 8}{4} = \frac{3}{8} + \frac{16}{8}$

Now, you can add the fractions since they have the same denominator:

$\frac{3 + 16}{8} = \frac{19}{8}$

So, $\frac{3}{8} + 2\frac{1}{4} = 2\frac{3}{8}$ or $\frac{19}{8}$ as an improper fraction.

b) $5\frac{2}{15} + 3\frac{2}{9}$

First, find a common denominator, which in this case is 45.

$5\frac{2}{15} + 3\frac{2}{9} = \frac{5 \cdot 3}{15} + \frac{3 \cdot 5}{9}$

Now, convert both fractions to have a denominator of 45:

$\frac{15}{45} + \frac{30}{45}$

Now, add the fractions with the same denominator:

$\frac{15 + 30}{45} = \frac{45}{45} = 1$

So, $5\frac{2}{15} + 3\frac{2}{9} = 1$.

c) $1\frac{3}{5} + 10\frac{1}{4}$

First, find a common denominator, which in this case is 20.

$1\frac{3}{5} + 10\frac{1}{4} = \frac{1 \cdot 4}{5} + \frac{10 \cdot 5}{4}$

Now, convert both fractions to have a denominator of 20:

$\frac{4}{20} + \frac{50}{20}$

Now, add the fractions with the same denominator:

$\frac{4 + 50}{20} = \frac{54}{20}$

Reduce the fraction to its simplest form:

$\frac{54}{20} = \frac{27}{10}$

So, $1\frac{3}{5} + 10\frac{1}{4} = 11\frac{1}{10}$ or $\frac{27}{10}$ as an improper fraction.
