## Simple Patterns 2

Directions: Using the digits 1 to 9 at most one time each, place a digit …

1. We had a variety of answers on this one, but one I did not expect was 7/ 3 4/8 = 2.0 Although I generally steer clear of complex fractions I thought this was a creative way to solve this “puzzle.”

2. I figured out all the answers in less than a second

3. 1/5 = 0.2
2/5 = 0.4
3/5 = 0.6
4/5 = 0.8
3/2 = 1.5

If you allow two-digit numbers, it gets more fun:
48/30 = 1.6
34/20 = 1.7
… and I’m sure, many more.

4. A student and I found 19 different answers, the halves from above, the fifths from above, as well as some impropers like
7/5 =1.4
6/5 = 1.2
6/2 = 3.0
7/2 = 3.5
8/2 = 4.0
9/2 = 4.5
8/4 = 2.0
This was a fun one!

5. 58/100 = 0.58

• Good try, Ale, but remember that you can only use the digits at most one each time.

4/8 =0.5

7. right away i knew one.
1/4 0.25

8. 3/4 = 0.75
