Fraction Puzzle (Subtracting Unlike Denominators) | Printable ... - Free Printable

Looking at the crossword grid, I can see the layout of the puzzle with numbered squares for each problem. The grid shows that each answer needs to fit into a specific number of spaces, which will help me verify my calculations.

Let me now solve all the problems systematically and then fill in the grid:

Across:
3. 4/5 - 2/10 = 8/10 - 2/10 = 6/10 = 3/5
5. 5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2
7. 9/12 - 4/6 = 9/12 - 8/12 = 1/12
8. 1/2 - 1/8 = 4/8 - 1/8 = 3/8
12. 7/9 - 1/3 = 7/9 - 3/9 = 4/9
14. 2/3 - 1/6 = 4/6 - 1/6 = 3/6 = 1/2

Down:
1. 5/6 - 2/4 = 10/12 - 6/12 = 4/12 = 1/3
2. 1/2 - 1/4 = 2/4 - 1/4 = 1/4
3. 7/10 - 2/5 = 7/10 - 4/10 = 3/10
4. 2/4 - 1/2 = 1/2 - 1/2 = 0 (This seems problematic as 0 doesn't fit well in a fraction puzzle)
6. 2/3 - 1/6 = 4/6 - 1/6 = 3/6 = 1/2
9. 1/2 - 1/4 = 2/4 - 1/4 = 1/4
10. 4/5 - 4/10 = 8/10 - 4/10 = 4/10 = 2/5
11. 1/3 - 1/6 = 2/6 - 1/6 = 1/6
13. 1/2 - 2/4 = 1/2 - 1/2 = 0 (Again, this equals 0)

I notice that problems 4 and 13 both equal 0, which is unusual for a fraction puzzle. Let me double-check these:

Problem 4: 2/4 - 1/2
2/4 simplifies to 1/2, so 1/2 - 1/2 = 0

Problem 13: 1/2 - 2/4
2/4 simplifies to 1/2, so 1/2 - 1/2 = 0

These are mathematically correct, but perhaps in the context of this puzzle, they expect "0" to be written as a fraction like "0/1" or simply "0". Looking at the grid, I can see that each answer fits into a specific number of spaces, so I'll need to write the answers in their reduced form.

Let me also check problems 10 and 11:
10. 4/5 - 4/10 = 8/10 - 4/10 = 4/10 = 2/5
11. 1/3 - 1/6 = 2/6 - 1/6 = 1/6

Now let me look at the remaining problems I haven't fully solved yet:

Problem 6: 2/3 - 1/6 = 4/6 - 1/6 = 3/6 = 1/2
Problem 9: 1/2 - 1/4 = 2/4 - 1/4 = 1/4

I think I have all the solutions. Let me organize them:

Across:
3. 3/5
5. 1/2
7. 1/12
8. 3/8
12. 4/9
14. 1/2

Down:
1. 1/3
2. 1/4
3. 3/10
4. 0 (or 0/1)
6. 1/2
9. 1/4
10. 2/5
11. 1/6
13. 0 (or 0/1)

The answers would be filled into the crossword grid according to the numbered squares. For problems 4 and 13 that equal 0, I would write "0" in the grid, though it's unusual for a fraction puzzle.

Since the instructions say "Reduce to lowest terms. Write the difference in the puzzle. Do not forget the hyphens," I should write the fractions with hyphens (like "3-5" for 3/5) in the grid.

The solution to this fraction puzzle is to fill in the crossword grid with the reduced fraction answers for each problem, writing them with hyphens as instructed.
