Use the element method for proving that a set equals the empty set to prove following the statement. (Assume that all sets are subsets of a universal set U.) For all sets A, B, and C, if A ⊆ B and B ∩ C = ∅ then A ∩ C = ∅. Proof by contradiction: Consider the sentences in the following scrambled list.

So these can be translated to decimals
we know that 4=4/1 so 0.4=0.4/1, to convert to nice fractions, multiply by 10/10 and get 4/10 times 10/10=40/100

then 0.25/1 times 100/100=25/100 so
0.1/1 times 10/10=1/10

a farmer planted 40/100 or 4/10 or 2/5 of his field with corn
pumpkin=25/100=1/4 field with pumpkin
tomato=1/10 with tomato

you should be able to solve with this info
