0.2=1/5
I don't know if the last one is correct but the other two are.
Alright here we go.

Number 8= -2/5

Number 9 = -18.3/25

Number 10 = 1/5 ?

Number 8 = Divide -0.4 by 1 to get the fraction of -0.4/1 and multiply both sides by 5 to get simplified of -2/5.

Number 9 = Divide by 10 to get -7.32/10 and multiply by 100 to get -732/1000. Then divide both sides by 40 to get -18.3/25.

Number 10 = Might be right or wrong but since it's 0.2, this simplifies to 2/10, which equals 1/5.

Hope this helps.
