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.”

I figured out all the answers in less than a second

More answers…

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.

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!

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

Good!

right away i knew one.

1/4 0.25

3/4 = 0.75
