Answer 2

Let's simplify the given expressions:

1. $8 + \frac{2}{5}$:

To add a whole number and a fraction, you can first convert the whole number into a fraction with the same denominator as the fraction:

$8 = \frac{8}{1}$

Now, we have:

$\frac{8}{1} + \frac{2}{5}$

To add these fractions, they need a common denominator, which is 5. So, we can rewrite $\frac{8}{1}$ as $\frac{8}{1} \times \frac{5}{5} = \frac{40}{5}$.

Now, we can add the fractions:

$\frac{40}{5} + \frac{2}{5} = \frac{42}{5}$

So, $8 + \frac{2}{5} = \frac{42}{5}$.

2. $1 - \frac{18}{27}$:

First, we can simplify the fraction $\frac{18}{27}$ by finding a common factor to reduce it:

$18$ and $27$ both have a common factor of $9$, so we can simplify the fraction:

$\frac{18}{27} = \frac{18 \div 9}{27 \div 9} = \frac{2}{3}$

Now, we have:

$1 - \frac{2}{3}$

To subtract these fractions, they need a common denominator, which is 3. So, we can rewrite $1$ as $\frac{3}{3}$.

Now, we can subtract the fractions:

$\frac{3}{3} - \frac{2}{3} = \frac{1}{3}$

So, $1 - \frac{18}{27} = \frac{1}{3}$.
