Answer 1

\[\frac{8\times 10}{8+10}\] you can do the conversion

so i add them and divide and then convert?

Answer 3

yes it is

\[\frac{80}{18}\] which reduces easily

ok thanks!

Answer 5

i think you get \(4\tfrac{4}{9}\) which you then apparently have to convert to minuutes
maybe for hours and 28 minutes? 27 minutes? something like that
