Nice! I was going to submit one in a similar vein.

Using the numbers 1-9, at most one time each, fill in the boxes to create a correct sentence:

[] [] % of [] [] is [] []?

68% of 25 is 17

25 % 68 of is 17

25% of 76 is 19

76% of 25 is 19

92% of 75 is 69…

All of the solutions involve a 75 or a 25

Significantly harder:

Three digits!

Using the numbers 0-9, at most one time each, fill in the boxes to create a correct sentence:

[] [] [] % of [] [] []is [] [] [] ?

375 % 184 is 690.

348% of 175 is 609.

One answer out of many possible answers is 5% of 260 is 13

I got the same with my program 26 solutions.

My student got 8% of 950= 76. Is this a possible highest answer?

It is indeed!

It’s so easy I got 5% of 280=14

8% of 59=4.72

5% of 260=13 is one of the many solves for this problem

I did it this way

9% of 638 = 57

6% of 350= 21

68% of 50 is 34

6% of 350 = 21

6% = 0.06

350 * 0.06 = 21

5% of 640 is 32

5% is 0.05

640*0.05 is 32

8% of 950 = 76

2% of 650 = 13
