Answer 3

Sure, I can help you with these calculations:

1. $3 \frac{1}{3} - 2.5$:

First, let's convert the mixed number $3 \frac{1}{3}$ to an improper fraction:

$3 \frac{1}{3} = \frac{10}{3}$

Now, let's subtract $2.5$ from $\frac{10}{3}$:

$\frac{10}{3} - 2.5$

To subtract these, we need a common denominator, which in this case is 6:

$\frac{20}{6} - \frac{15}{6} = \frac{5}{6}$

So, $3 \frac{1}{3} - 2.5 = \frac{5}{6}$.

2. $4.9 + 1 \frac{1}{9}$:

First, let's convert the mixed number $1 \frac{1}{9}$ to an improper fraction:

$1 \frac{1}{9} = \frac{10}{9}$

Now, let's add $4.9$ to $\frac{10}{9}$:

$4.9 + \frac{10}{9}$

To add these, we need a common denominator, which in this case is 9:

$4.9 + \frac{10}{9} = \frac{44}{9}$

So, $4.9 + 1 \frac{1}{9} = \frac{44}{9}$.
