The answer would be 8.
REMEMBER: Keep / Change / Flip
KEEP - 4/5
CHANGE - / to *
FLIP - 1/10 | 10/1
Now you have, 4/5 * 10/1. Just multiple across and you'll get 40/5. Now, divide 40 and 5 and you'll get your answer, 8.
[tex] \frac{ \frac{4}{5} }{ \frac{1}{10} } [/tex]
[tex] \frac{4}{5} \div \frac{1}{10} [/tex]
[tex] \frac{4}{5} \times \frac{10}{1} [/tex]
[tex] \frac{40}{5} [/tex]
[tex]8[/tex]
