Alabama State Test Practice

Correct answer: A

The correct answer is $\frac{7}{8}$.

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: Rewrite $\frac{3}{4}$ as $\frac{6}{8}$. Then $\frac{6}{8}+\frac{1}{8}=\frac{7}{8}$.
3. Check the result: Compare the result with the choices. The correct choice is $\frac{7}{8}$.

Correct answer: B

The correct answer is $7.5$.

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: Multiplying by 10 moves the decimal point one place to the right, so 0.75 becomes 7.5.
3. Check the result: Compare the result with the choices. The correct choice is $7.5$.

Correct answer: C

The correct answer is 40 beads.

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: The scale factor is 5 because 3 × 5 = 15. The total ratio is 8, so 8 × 5 = 40 beads.
3. Check the result: Compare the result with the choices. The correct choice is 40 beads.

Correct answer: D

The correct answer is $x=4$.

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: Subtract 3 from both sides to get 2x = 8, then divide by 2 to get x = 4.
3. Check the result: Compare the result with the choices. The correct choice is $x=4$.

Correct answer: A

The correct answer is 20.

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: 25% is one fourth. One fourth of 80 is 20.
3. Check the result: Compare the result with the choices. The correct choice is 20.

Correct answer: B

The correct answer is $4\cdot3+4\cdot2$.

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: The distributive property gives $4(3+2)=4\cdot3+4\cdot2$.
3. Check the result: Compare the result with the choices. The correct choice is $4\cdot3+4\cdot2$.

Correct answer: C

The correct answer is 12 stickers.

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: One third of 18 is 6. Subtracting 6 from 18 leaves 12 stickers.
3. Check the result: Compare the result with the choices. The correct choice is 12 stickers.

Correct answer: D

The correct answer is Add 4 each time..

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: Each term is 4 greater than the previous term, so the rule is add 4.
3. Check the result: Compare the result with the choices. The correct choice is Add 4 each time..

Correct answer: A

The correct answer is $0.62$.

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: Write the numbers with three decimal places: 0.620, 0.600, 0.602, and 0.260. Therefore 0.62 is greatest.
3. Check the result: Compare the result with the choices. The correct choice is $0.62$.

Correct answer: B

The correct answer is $n+7=19$.

1. Identify what the question asks: Read the passage, data, or mathematical expression carefully and identify the evidence or operation needed.
2. Apply the strategy: The unknown number n is increased by 7, so n + 7 equals the result 19.
3. Check the result: Compare the result with the choices. The correct choice is $n+7=19$.
