Sample New Jersey NJSLA-Adaptive Math Grade 8 Practice Questions

Try these sample questions to test your New Jersey NJSLA-Adaptive Math Grade 8 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What fraction is equivalent to the repeating decimal 0.888...?
A.8/9
B.4/5
C.9/10
D.8/11
Explanation: A repeating decimal with one repeating digit d equals d/9, so 0.888... = 8/9.
2Write the repeating decimal 0.272727... as a fraction in simplest form.
A.3/11
B.27/100
C.3/10
D.27/101
Explanation: A two-digit repeating decimal 0.abab... equals ab/99, so 0.2727... = 27/99, which simplifies to 3/11.
3Which of the following numbers is irrational?
A.√2
B.0.5
C.−3
D.7/2
Explanation: An irrational number cannot be written as a ratio of integers; the square root of 2 has a non-terminating, non-repeating decimal expansion, so it is irrational.
4Between which two consecutive integers does √8 lie?
A.Between 2 and 3
B.Between 3 and 4
C.Between 1 and 2
D.Between 2 and 4
Explanation: Since 2 squared equals 4 and 3 squared equals 9, and 4 is less than 8 which is less than 9, the square root of 8 lies strictly between 2 and 3.
5Convert the repeating decimal 0.1666... to a fraction in simplest form.
A.1/6
B.1/5
C.1/7
D.1/16
Explanation: Let x = 0.1666...; then 10x = 1.666... and 100x = 16.666..., so 90x = 15, giving x = 15/90 = 1/6.
6Use a rational approximation to estimate √20 to the nearest tenth.
A.4.5
B.4.2
C.5.0
D.4.7
Explanation: Since 4 squared equals 16 and 5 squared equals 20, the square root of 20 is near but below 5; 4.4 squared equals 19.36 and 4.5 squared equals 20.25, so the square root of 20 is about 4.5 to the nearest tenth.
7Between which two consecutive integers does √13 lie, and which integer is it closer to?
A.Between 3 and 4, closer to 4
B.Between 3 and 4, closer to 3
C.Between 4 and 5, closer to 4
D.Between 2 and 3, closer to 3
Explanation: Since 3 squared equals 9 and 4 squared equals 16, the square root of 13 is about 3.6, between 3 and 4; because 3.6 is 0.4 from 4 but 0.6 from 3, it is closer to 4.
8Which number in this list is irrational?
A.√7
B.√16
C.0.333...
D.−5/3
Explanation: The square root of 7 cannot be expressed as a ratio of integers and has a non-terminating, non-repeating decimal, so it is irrational.
9Using approximations √2 ≈ 1.414 and √3 ≈ 1.732, which is larger: 2√3 or 3√2?
A.3√2
B.2√3
C.They are equal
D.Cannot be determined
Explanation: Using the given approximations, 3 times the square root of 2 is about 3(1.414) = 4.243, while 2 times the square root of 3 is about 2(1.732) = 3.464, so 3 times the square root of 2 is larger.
10The fraction 22/7 is a common rational approximation of π. Which statement is true?
A.22/7 is slightly greater than π
B.22/7 is slightly less than π
C.22/7 equals π exactly
D.22/7 is not close to π
Explanation: 22/7 is about 3.1429 while pi is about 3.1416, so 22/7 exceeds pi by about 0.0013; as a rational number it approximates but cannot equal the irrational pi.

New Jersey NJSLA-Adaptive Math Grade 8 Study Tips from Top Performers

1Keep exponents consistent when multiplying powers: add exponents with the same base.
2Rewrite scientific notation numbers with matching powers of 10 before you add or subtract.
3Isolate the variable in a linear equation by doing the same inverse operation on both sides.
4Use the Pythagorean theorem to find a missing side, then check that the longest side is the hypotenuse.
5Tell linear from nonlinear functions by checking whether the rate of change is constant.
