I'll solve each problem on this math worksheet step by step.

## WEDNESDAY PROBLEMS:

Problem 1: Write the equivalent fraction
- We have 1/3 = □/□
- Looking at the visual model, we need to find an equivalent fraction
- If we multiply both numerator and denominator by 2: 1×2 / 3×2 = 2/6
- Answer: 1/3 = 2/6

Problem 2: Find the perimeter
- Rectangle with length = 3 in. and width = 2 in.
- Perimeter formula: P = 2(length + width)
- P = 2(3 + 2) = 2(5) = 10 inches
- Answer: p = 10 in.

Problem 3: Shade in the rectangles
- Rectangles are four-sided shapes with opposite sides equal and all angles 90°
- The first shape (horizontal rectangle) - YES, it's a rectangle
- The second shape (diamond/rhombus) - NO, not a rectangle
- The third shape (vertical rectangle) - YES, it's a rectangle
- The fourth shape (tilted parallelogram) - NO, not a rectangle
- Answer: Shade the 1st and 3rd shapes

Problem 4: Sam has 15 apples
- 15 apples divided equally among 3 plates
- 15 ÷ 3 = 5 apples per plate
- Answer: 5 apples on each plate

Problem 5: Find the area of the L-shaped figure
- This is an L-shape that can be split into two rectangles
- Method 1: Split vertically
- Left rectangle: 8 in. × 4 in. = 32 sq. in.
- Right rectangle: 4 in. × 4 in. = 16 sq. in.
- Total: 32 + 16 = 48 sq. in.
- Method 2: Large rectangle minus missing piece
- Full rectangle would be: 8 in. × 8 in. = 64 sq. in.
- Missing piece: 4 in. × 4 in. = 16 sq. in.
- Area: 64 - 16 = 48 sq. in.
- Answer: 48 square inches

## THURSDAY PROBLEMS:

Eye Colors Bar Graph Questions:

Looking at the bar graph:
- Brown eyes: 8 students
- Blue eyes: 12 students
- Hazel eyes: 5 students
- Green eyes: 3 students

Question 1: How many students have hazel eyes?
- Answer: 5 students

Question 2: How many more students have blue eyes than brown?
- Blue: 12, Brown: 8
- 12 - 8 = 4
- Answer: 4 more students

Question 3: How many fewer students have green eyes than brown?
- Brown: 8, Green: 3
- 8 - 3 = 5
- Answer: 5 fewer students

Problem 4: Ally's grapes
- Start: 7 grapes
- Eats 2: 7 - 2 = 5
- Gives away 3: 5 - 3 = 2
- g = 2
- Answers:
- 7 - 2 = 5
- 5 - 3 = 2
- g = 2
- She has 2 grapes left

Problem 5: Compare the fractions
- Comparing 1/2 and 1/4
- 1/2 means 1 out of 2 parts (larger pieces)
- 1/4 means 1 out of 4 parts (smaller pieces)
- 1/2 > 1/4
- Answer: 1/2 > 1/4

Final Answer:

WEDNESDAY:
1. 1/3 = 2/6
2. p = 10 in.
3. Shade the 1st and 3rd shapes (the horizontal and vertical rectangles)
4. 5 apples on each plate
5. 48 square inches

THURSDAY:
1. 5 students
2. 4 more students
3. 5 fewer students
4. 7 - 2 = 5; 5 - 3 = 2; g = 2; She has 2 grapes left
5. 1/2 > 1/4
