Answer :

To simplify the expression [tex]\(\sqrt{\frac{16}{25}}\)[/tex], let's follow these steps:

### Step 1: Express the square root of the fraction as a fraction of square roots

The square root of a fraction can be written as the fraction of the square roots of the numerator and the denominator:
[tex]\[ \sqrt{\frac{16}{25}} = \frac{\sqrt{16}}{\sqrt{25}} \][/tex]

### Step 2: Simplify the square root of the numerator

Next, simplify [tex]\(\sqrt{16}\)[/tex]:
[tex]\[ \sqrt{16} = 4 \][/tex]

### Step 3: Simplify the square root of the denominator

Now, simplify [tex]\(\sqrt{25}\)[/tex]:
[tex]\[ \sqrt{25} = 5 \][/tex]

### Step 4: Write the simplified form of the fraction

Putting the simplified numerator and denominator together, we get:
[tex]\[ \frac{\sqrt{16}}{\sqrt{25}} = \frac{4}{5} \][/tex]

### Step 5: Recalculate the fraction if needed

There is no further simplification needed since [tex]\( \frac{4}{5} \)[/tex] is already in its simplest form.

### Conclusion

The simplified form of the expression [tex]\(\sqrt{\frac{16}{25}}\)[/tex] is:
[tex]\[ \frac{4}{5} \][/tex]

Thus, [tex]\(\sqrt{\frac{16}{25}} = \frac{4}{5}\)[/tex], and since [tex]\(\frac{4}{5} = 0.8\)[/tex]:

\boxed{\frac{4}{5}, 0.8}
