Answer 1

`3(4)/(5)`

Explanation:

let the unknown number be x, therefore we have:

`4* x(5)/(7)=10(6)/(7)`

we rewrite our equation to solve for x by grouping like terms:

`x(5)/(7)=(10(6)/(7))/(4)\\\\x(5)/(7)=2(5)/(7)\\\\(7)/(5)* x(5)/(7)=(19)/(7)* (7)/(5)\\\\\\x=(19)/(5)\\\\x=3(4)/(5)`

Hence, the unknown number is
`3(4)/(5)`
