Sample Puerto Rico CRECE Grade 8 Mathematics Assessment Practice Questions

Try these sample questions to test your Puerto Rico CRECE Grade 8 Mathematics Assessment exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following numbers is an irrational number?
A.$\frac{7}{8}$
B.$\sqrt{49}$
C.$\sqrt{18}$
D.$0.35$
Explanation: An irrational number cannot be expressed as a ratio of two integers. $\sqrt{18} = 3\sqrt{2}$ has a non-terminating, non-repeating decimal expansion. The other options are rational: $\frac{7}{8}$ and $0.35$ are ratios of integers, and $\sqrt{49} = 7$.
2Between which two consecutive integers does $\sqrt{53}$ lie on a number line?
A.$6$ and $7$
B.$7$ and $8$
C.$8$ and $9$
D.$5$ and $6$
Explanation: Identify perfect squares near 53: $7^2 = 49$ and $8^2 = 64$. Since $49 < 53 < 64$, taking the square root gives $\sqrt{49} < \sqrt{53} < \sqrt{64}$, which simplifies to $7 < \sqrt{53} < 8$.
3Convert the repeating decimal $0.444...$ ($0.\bar{4}$) to a fraction in simplest form.
A.$\frac{4}{9}$
B.$\frac{2}{5}$
C.$\frac{4}{10}$
D.$\frac{4}{11}$
Explanation: Let $x = 0.\bar{4}$. Multiply by 10 to get $10x = 4.\bar{4}$. Subtracting the original equation ($10x - x = 4.\bar{4} - 0.\bar{4}$) yields $9x = 4$, so $x = \frac{4}{9}$.
4Simplify the expression $3^4 \cdot 3^5$.
A.$3^{20}$
B.$9^9$
C.$3^9$
D.$9^{20}$
Explanation: When multiplying exponential expressions with the same base, add the exponents: $a^m \cdot a^n = a^{m+n}$. Here, $3^4 \cdot 3^5 = 3^{4+5} = 3^9$.
5Simplify $\frac{x^8}{x^{-3}}$ for $x \neq 0$.
A.$x^5$
B.$x^{11}$
C.$x^{-24}$
D.$x^{-5}$
Explanation: Using the quotient rule for exponents, $\frac{a^m}{a^n} = a^{m-n}$. Subtract the bottom exponent from the top exponent: $8 - (-3) = 8 + 3 = 11$, giving $x^{11}$.
6Simplify $(2x^3 y^{-2})^3$ and express with exponents.
A.$6x^9 y^{-6}$
B.$8x^9 y^{-6}$
C.$8x^6 y^1$
D.$6x^6 y^{-5}$
Explanation: Apply power of a product and power of a power rules: $(a \cdot b)^n = a^n b^n$ and $(x^m)^n = x^{m \cdot n}$. Thus, $2^3 \cdot x^{3 \cdot 3} \cdot y^{-2 \cdot 3} = 8x^9 y^{-6}$.
7Express $0.00045$ in scientific notation.
A.$4.5 \times 10^{-4}$
B.$4.5 \times 10^{-5}$
C.$45 \times 10^{-5}$
D.$4.5 \times 10^4$
Explanation: Move the decimal point 4 places to the right to obtain a coefficient between 1 and 10 ($4.5$). Since the original number is less than 1, the exponent is negative 4: $4.5 \times 10^{-4}$.
8Evaluate $(3 \times 10^4) \times (5 \times 10^6)$ and express the result in scientific notation.
A.$1.5 \times 10^{11}$
B.$15 \times 10^{10}$
C.$1.5 \times 10^{10}$
D.$8 \times 10^{10}$
Explanation: Multiply coefficients: $3 \times 5 = 15$. Add exponents: $10^4 \times 10^6 = 10^{10}$. So $15 \times 10^{10} = 1.5 \times 10^{11}$ in proper scientific notation.
9Evaluate $\frac{8.4 \times 10^8}{2.1 \times 10^3}$ and express the answer in scientific notation.
A.$4.0 \times 10^5$
B.$4.0 \times 10^{11}$
C.$6.3 \times 10^5$
D.$4.0 \times 10^{24}$
Explanation: Divide the coefficients: $8.4 \div 2.1 = 4.0$. Subtract the powers of ten: $10^{8-3} = 10^5$. Combine to get $4.0 \times 10^5$.
10Calculate $(4.2 \times 10^5) + (3.8 \times 10^4)$ and express the result in scientific notation.
A.$4.58 \times 10^5$
B.$8.0 \times 10^9$
C.$8.0 \times 10^5$
D.$4.58 \times 10^4$
Explanation: Convert terms to the same power of ten: $3.8 \times 10^4 = 0.38 \times 10^5$. Add coefficients: $(4.2 + 0.38) \times 10^5 = 4.58 \times 10^5$.

About the Puerto Rico CRECE Grade 8 Mathematics Assessment Exam

The Puerto Rico CRECE (Cernimiento, Revisión y Evaluación Continua del Estudiante (CRECE)) Grade 8 Mathematics assessment evaluates 8th-grade students across public schools in Puerto Rico on core mathematical competencies established in the Puerto Rico Core Standards (PRCS 2022).
