Fraction: A number representing part of a whole
Numerator: The top number in a fraction
Denominator: The bottom number in a fraction
Visual: Circle divided into 4 equal parts
Shaded: 2 parts are shaded
Answer: \(\frac{2}{4}\)
Circle is divided into 4 equal parts
2 parts are shaded
Shaded parts over total parts = \(\frac{2}{4}\)
Option B is correct
The circle is divided into 4 equal parts, and 2 parts are shaded. Therefore, the fraction is \(\frac{2}{4}\).
• Equal parts: All divisions must be equal
• Part-to-whole: Shaded parts over total parts
• Visual counting: Count both shaded and total parts
A) \(\frac{1}{3}\) B) \(\frac{1}{4}\) C) They are equal D) Cannot determine
Compare: \(\frac{1}{3}\) vs \(\frac{1}{4}\)
Same numerator: 1 in both fractions
Different denominators: 3 vs 4
\(\frac{1}{3}\) means 1 part out of 3 equal parts
With same numerator, smaller denominator means larger fraction
3 is smaller than 4, so \(\frac{1}{3}\) is larger
Option A is correct
When fractions have the same numerator, the one with the smaller denominator is larger. So \(\frac{1}{3} > \frac{1}{4}\).
• Same numerator rule: Smaller denominator = larger fraction
• Comparison principle: Denominator affects fraction size inversely
• Logical reasoning: More parts mean smaller individual parts
Parts taken: 3
Total parts: 8
Fraction: \(\frac{3}{8}\)
Numerator is 3 (parts taken)
Denominator is 8 (total parts)
Numerator over denominator = \(\frac{3}{8}\)
\(\frac{3}{8}\)
When 3 parts are taken out of 8 equal parts, the fraction is \(\frac{3}{8}\).
• Numerator identification: Parts taken
• Denominator identification: Total parts
• Fraction formation: Parts taken over total parts
A) Closer to 0 B) Closer to 1 C) Exactly in the middle D) At 0
Fraction: \(\frac{3}{4}\)
Range: Between 0 and 1
Position: Three-quarters of the way from 0 to 1
\(\frac{3}{4}\) means 3 out of 4 equal parts
\(\frac{3}{4} = 0.75\), which is closer to 1 than to 0
Three-quarters is much closer to 1 than to 0
Option B is correct
\(\frac{3}{4}\) is located three-quarters of the way from 0 to 1, which is much closer to 1 than to 0.
• Number line positioning: Fractions positioned by value
• Decimal conversion: \(\frac{3}{4} = 0.75\)
• Distance comparison: Compare to 0.5 (middle point)
A) \(\frac{2}{3}\) B) \(\frac{2}{4}\) C) \(\frac{3}{4}\) D) \(\frac{1}{4}\)
Target: Fraction equivalent to \(\frac{1}{2}\)
Check: Which option equals \(\frac{1}{2}\)
Answer: \(\frac{2}{4} = \frac{1}{2}\)
Equivalent fractions represent the same amount
\(\frac{2}{4} = \frac{1}{2}\) (divide numerator and denominator by 2)
Other options do not equal \(\frac{1}{2}\)
Option B is correct
\(\frac{2}{4}\) simplifies to \(\frac{1}{2}\) when both numerator and denominator are divided by 2.
• Equivalence principle: Fractions that simplify to same value
• Simplification rule: Divide both parts by common factor
• Verification method: Check by simplifying
Fraction: \(\frac{2}{5}\)
Required: Visual representation
Elements: 5 equal parts with 2 shaded
Create 5 equal sections (rectangles, circles, etc.)
Shade exactly 2 of the 5 parts
Ensure all 5 parts are the same size
2 shaded parts out of 5 total parts
Any visual model with 5 equal parts and 2 shaded represents \(\frac{2}{5}\).
• Equal parts requirement: All divisions must be equal
• Visual representation: Model must show fraction accurately
• Counting verification: Check shaded vs total parts
Fraction: \(\frac{1}{2}\)
Range: Between 0 and 1
Position: Exactly in the middle
Create a line from 0 to 1
\(\frac{1}{2}\) is exactly halfway between 0 and 1
Place a point at the center of the line
Mark as \(\frac{1}{2}\)
\(\frac{1}{2}\) appears exactly in the middle of the number line between 0 and 1.
• Midpoint location: \(\frac{1}{2}\) is at the center
• Equal spacing: Maintain consistent intervals
• Position accuracy: Precise placement required
Total cookies: 12
Fraction eaten: \(\frac{1}{4}\)
Calculation: \(\frac{1}{4} \times 12\)
Total = 12 cookies, Fraction = \(\frac{1}{4}\)
12 ÷ 4 = 3
3 × 1 = 3
Emma ate 3 cookies
\(\frac{1}{4}\) of 12 cookies equals 3 cookies (\(\frac{1}{4} \times 12 = 3\)).
• Fraction of whole: Divide by denominator, multiply by numerator
• Real-world context: Apply math to practical situation
• Arithmetic steps: Follow order of operations
Total pages: 20
Fraction read: \(\frac{3}{5}\)
Calculation: \(\frac{3}{5} \times 20\)
Total = 20 pages, Fraction = \(\frac{3}{5}\)
20 ÷ 5 = 4
4 × 3 = 12
Tom read 12 pages
\(\frac{3}{5}\) of 20 pages equals 12 pages (\(\frac{3}{5} \times 20 = 12\)).

Fractions to compare: \(\frac{1}{4}\), \(\frac{1}{2}\), \(\frac{1}{3}\), \(\frac{3}{4}\)
Order: Smallest to largest
Method: Convert to decimals or find common denominator
\(\frac{1}{4} = 0.25\), \(\frac{1}{3} = 0.33\), \(\frac{1}{2} = 0.5\), \(\frac{3}{4} = 0.75\)
0.25 < 0.33 < 0.5 < 0.75
\(\frac{1}{4} < \frac{1}{3} < \frac{1}{2} < \frac{3}{4}\)
\(\frac{1}{4}\), \(\frac{1}{3}\), \(\frac{1}{2}\), \(\frac{3}{4}\)
When arranged from smallest to largest: \(\frac{1}{4} < \frac{1}{3} < \frac{1}{2} < \frac{3}{4}\).
