Answer 1

it will be B) 6/5 because thats the only thing that would get you a greater number then 2/3

Answer 2

The correct option is B.

Explanation:

If a number n is multiply by a number than lies between 0 to 1, then the product is less than the initial number.

`k* n<n` if 0<k<1

If a number n is multiply by a number that is greater than 1, then the product is greater than the initial number.

`k* n>n` if k>1

It is given that Fiona multiplies a number by 2/3.The product is greater than 2/3. It means the number which is multiplies by Fiona is must be greater than 1.

`(10)/(12)<1`

`(6)/(5)<1`

`(3)/(3)=1`

`(2)/(9)<1`

That number is
`(6)/(5)`. Therefore the correct option is B.
