Open Middle®
Directions: Use the digits 1 to 9, at most one time each, to make a difference with the least possible value.
Hint
How do you place digits so the difference is less than ten?
Answer
The least possible value is 1.2 and you can get it using:
8.5 – 7.3 = 1.2
6.9 – 5.7 = 1.2
8.5 – 7.3 = 1.2
6.9 – 5.7 = 1.2

Also, 9.5 – 8.3 = 1.2???
4.9 – 3.7
8.4-7.3? Couldn’t you get 1.1?
No because then you would have two 1’s.
Disregard, realized 1 is repeated in the answer.
My name is Brigid from 5th grade and I also found 4.7-3.5=1.2
9.7-8.5=1.2
1.2-3.4=2.2
i agree
4.7-3.5=1.2
The least possible value is 1.2 and you can get it using:
8.5 – 7.3 = 1.2
6.9 – 5.7 = 1.2
9.8-7.5=2.3
The least possible value is:1.2
8.4 – 7.4= 1.2
5.4-4.4=1.2
I got an answer of 6.9-5.7=1.2
