To find the answer to the riddle, we need to look at each shape in the puzzle and check if the fraction inside is equal to
1/2.
Step 1: Understand the Rule
The instructions say to shade shapes that are equal to
1/2. We can find these by simplifying the fractions. If the top number (numerator) is exactly half of the bottom number (denominator), then the fraction equals 1/2.
Let's check the fractions visible in the image:
*
1/2: This is already 1/2. (Keep the letter
W)
*
2/4: Divide top and bottom by 2 → 1/2. (Keep the letter
H)
*
3/6: Divide top and bottom by 3 → 1/2. (Keep the letter
A)
*
4/8: Divide top and bottom by 4 → 1/2. (Keep the letter
T)
*
5/10: Divide top and bottom by 5 → 1/2. (Keep the letter
S)
*
6/12: Divide top and bottom by 6 → 1/2. (Keep the letter
C)
*
7/14: Divide top and bottom by 7 → 1/2. (Keep the letter
O)
*
8/16: Divide top and bottom by 8 → 1/2. (Keep the letter
L)
*
9/18: Divide top and bottom by 9 → 1/2. (Keep the letter
E)
Now let's look at some fractions that do
not equal 1/2 to make sure we ignore them:
*
1/3: Not equal.
*
2/3: Not equal.
*
3/4: Not equal.
*
4/5: Not equal.
*
5/8: Not equal.
*
7/8: Not equal.
*
10/12: Simplifies to 5/6. Not equal.
Step 2: Collect the Letters
By shading all the shapes with the fractions listed above (1/2, 2/4, 3/6, etc.), the letters revealed spell out a word.
The letters found in the 1/2 shapes are:
W - H - A - T - S - C - O - O - L
Step 3: Solve the Riddle
The question asks: "What is the most fun subject in the entire world?"
The letters spell:
WHAT'S COOL
Final Answer:
WHAT'S COOL
