* Step 1: Look at the hundreds place.
* 10,504 (5 hundreds) is the greatest.
* 10,405 (4 hundreds) is next.
* 10,005 (0 hundreds) is the least.
* Final Answer: B. 10,504; 10,405; 10,005 *(Note: Option B in the image lists them Greatest to Least correctly based on standard test formats, though the text in the image for B is "10,005, 10,504, 10,405" which is mixed up. Looking closely at Option A: "10,005, 10,405, 10,504" is Least to Greatest. Option C: "10,504, 10,405, 10,005" is Greatest to Least.)*
* Correction: The question asks for Greatest to Least.
* Greatest: 10,504
* Middle: 10,405

Geometry (Angles)

Question 21: What is the measure of the angle of the shaded portion in degrees? (Image shows a circle divided into 4 equal parts, 1 part shaded).
* Step 1: A full circle is $360^{\circ}$.
* Step 2: It is divided into 4 equal parts.
* Step 3: $360 \div 4 = 90$.
* Final Answer: D. $90^{\circ}$

Subtraction

Question 25: $597,805 - 103,651$
* Step 1: Ones: $5 - 1 = 4$.
* Step 2: Tens: $0 - 5$ (borrow from hundreds). $10 - 5 = 5$.
* Step 3: Hundreds: $7 - 6 = 1$ (since we borrowed from the 8, it became 7).
* Step 4: Thousands: $7 - 3 = 4$.
* Step 5: Ten-thousands: $9 - 0 = 9$.
* Step 6: Hundred-thousands: $5 - 1 = 4$.
* Result: 494,154.
* Final Answer: D. 494,154

Common Denominators

Question 26: Write $\frac{1}{8}$ and $\frac{3}{5}$ as a pair of fractions with common denominators.
* Step 1: Find a common multiple for 8 and 5. $8 \times 5 = 40$.
* Step 2: Convert $\frac{1}{8}$: Multiply top and bottom by 5 $\rightarrow \frac{5}{40}$.
* Step 3: Convert $\frac{3}{5}$: Multiply top and bottom by 8 $\rightarrow \frac{24}{40}$.
* *Note: The options in the image seem to use 15 or 8/15. Let's look at Option B: $\frac{5}{15}$ and $\frac{9}{15}$. This implies the original fractions might have been $\frac{1}{3}$ and $\frac{3}{5}$? No, the text clearly says $\frac{1}{8}$ and $\frac{3}{5}$. Let's re-read the options.*
* Actually, looking at Question 26 closely, the options are:
A. $\frac{1}{8}$ and $\frac{3}{8}$
B. $\frac{5}{15}$ and $\frac{9}{15}$ (This works for $\frac{1}{3}$ and $\frac{3}{5}$)
C. $\frac{3}{15}$ and $\frac{9}{15}$
D. $\frac{5}{15}$ and $\frac{6}{15}$
*There seems to be a typo in the worksheet question or options provided in the image for Q26. However, typically these tests look for the Least Common Denominator. If the question meant $\frac{1}{3}$ and $\frac{3}{5}$, the answer is B. If it strictly says $\frac{1}{8}$ and $\frac{3}{5}$, none of the visible options are correct (LCD is 40).*
*Let's assume the question text in the image has a typo and meant $\frac{1}{3}$ and $\frac{3}{5}$ based on Option B being a valid mathematical pair for those numbers.*

Fraction Subtraction

Question 27: $\frac{9}{11} - \frac{7}{11} =$
* Step 1: Subtract the numerators: $9 - 7 = 2$.
* Step 2: Keep the denominator the same: 11.
* Final Answer: A. $\frac{2}{11}$

Patterns (Multiplication)

Question 29: Complete the pattern:
$6 \times 7 = 42$
$6 \times 70 = 420$
$6 \times 700 = 4,200$
$6 \times 7,000 =$ \_\_\_\_
* Step 1: Multiply $6 \times 7 = 42$.
* Step 2: Add the three zeros from 7,000.
* Result: 42,000.
* Final Answer: C. 42,000

Data Analysis (Dot Plot)

Question 28: How many students walked their dog $\frac{1}{2}$ mile?
* Step 1: Look at the dot plot above the label "$\frac{1}{2}$".
* Step 2: Count the dots. There are 2 dots.
* Final Answer: C. 2

Geometry (Parallel Lines)

Question 49: Which 2 sides are parallel? (Trapezoid ABCD)
* Step 1: Parallel lines never touch and run in the same direction.
* Step 2: In the trapezoid shown, the top side (AB) and the bottom side (DC) are horizontal and parallel. The sides AD and BC are slanted.
* Final Answer: B. AB and DC

Geometry (Area)

Question 37: What is the area? (Rectangle with length 9 and width 3... wait, looking at Q37 in the yellow sheet).
* The shape is an L-shape or composite.
* Left rectangle: Height 5, Width ? (Top says 3). Let's look closer.
* It looks like two rectangles.
* Top/Left part: $3 \times 3 = 9$? No.
* Let's decompose it vertically.
* Left Rectangle: Height 5, Width 3. Area = $5 \times 3 = 15$.
* Right Rectangle attached to the side? The diagram shows a large rectangle $5 \times 3$ and a smaller one attached?
* Actually, let's look at the labels. Left side is 5. Top left is 3. Bottom right extension is 3 high? And width 3?
* Let's try splitting it horizontally.
* Top rectangle: $3 \text{ (width)} \times ?$
* Bottom rectangle: $? \times ?$
* Let's try splitting vertically.
* Left Rectangle: $5 \times 3 = 15$.
* Right Rectangle: The height is labeled 3. The width is labeled 3. Area = $3 \times 3 = 9$.
* Total Area = $15 + 9 = 24$.
* Final Answer: B. 24

Fraction Multiplication

Question 40: $\frac{1}{5} \times 3 =$
* Step 1: Multiply the numerator by the whole number: $1 \times 3 = 3$.
* Step 2: Keep the denominator the same: 5.
* Final Answer: B. $\frac{3}{5}$

Angle Types

Question 43: What type of angle is shown below? (Angle is greater than 90 but less than 180).
* Step 1: A right angle is exactly 90 (square corner).
* Step 2: An acute angle is smaller than 90.
* Step 3: An obtuse angle is larger than 90 but smaller than 180.
* Step 4: The angle shown is wide/open, clearly more than 90.
* Final Answer: B. Obtuse

Adding Fractions with Powers of 10

Question 50: $\frac{1}{10} + \frac{50}{100} =$
* Step 1: Convert $\frac{1}{10}$ to hundredths so the denominators match. Multiply top and bottom by 10: $\frac{10}{100}$.
* Step 2: Add $\frac{10}{100} + \frac{50}{100} = \frac{60}{100}$.
* Final Answer: A. $\frac{60}{100}$
