Step-by-step solution

Let's convert 0.3 to a simple fraction:

0.3=310 -0.3=-\frac{3}{10}

Let's convert 0.8 to a simple fraction:

0.8=810 -0.8=-\frac{8}{10}

Now the problem we received is:

310:810= -\frac{3}{10}:-\frac{8}{10}=

Let's convert the division problem to a multiplication problem, and don't forget to switch the numerator and denominator in the second fraction:

310×108= -\frac{3}{10}\times-\frac{10}{8}=

Let's simplify the 10 and we get:

38 \frac{3}{8}
