Answer:
w = 0.9
Explanation:
What I did is I subtracted 2.7 from 3.7 bc it was the least number and that gave me 1 so that left me with 0.43 = w - 0.47. Then I added 0.47 to 0.43 and that gives me 0.9 which would be the answer
If you don't understand how I got it I can try to explain a little better, but hopefully, you understand:)
