Answer 1

18/20 and 27/30 hope this helps

Answer 2

The answer is
`(18)/(20)` and
`(27)/(30)`

Explanation:

A multiple of any fraction number is the amplifyng of the base fraction with a same integer number, excluding the number zero, both in the numerator and in the denominator.

Give a fraction number
`(x)/(y)`

A Multiple is
`(n*x)/(n*y)`, where n is an integer without zero

So, using n=2 and n=3

For n=2,
`(2*9)/(2*10) =(18)/(20)`

For n=3,
`(3*9)/(3*10) =(27)/(30)`
