Sample RICAS Math Grade 8 Practice Questions

Try these sample questions to test your RICAS 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.

1Which of the following numbers is irrational?

A.√49

B.0.75

C.√18

D.22/7

Explanation: √18 is an irrational number because 18 is not a perfect square, so its square root cannot be written as a ratio of two integers and has a non-terminating, non-repeating decimal expansion.

2Which set contains ONLY rational numbers?

A.{-3, 0, √16, 5/9}

B.{√2, π, 3.14, 0}

C.{√9, √12, 4/5, -1}

D.{0.333..., √5, 7, -2}

Explanation: {-3, 0, √16, 5/9} contains only rational numbers: -3 and 0 are integers, √16 = 4, and 5/9 is a fraction of integers.

3Why is π (pi) classified as an irrational number?

A.It can be written as a repeating decimal.

B.It cannot be written as a ratio of two integers and its decimal expansion is non-terminating and non-repeating.

C.It is equal to 22/7 exactly.

D.It is a negative real number.

Explanation: By definition, an irrational number cannot be expressed as a fraction a/b of two integers; pi has an infinite non-repeating decimal expansion.

4Solve for x in the equation x^3 = 64.

A.x = 4

B.x = 8

C.x = 16

D.x = 21.33

Explanation: Taking the cube root of both sides gives x = ∛64. Since 4 * 4 * 4 = 64, x = 4.

5What is the value of √144 - ∛27?

A.9

B.15

C.141

D.11

Explanation: √144 = 12 because 12^2 = 144. ∛27 = 3 because 3^3 = 27. Therefore, 12 - 3 = 9.

6Between which two consecutive whole numbers does √65 lie?

A.7 and 8

B.8 and 9

C.9 and 10

D.6 and 7

Explanation: Since 8^2 = 64 and 9^2 = 81, and 64 < 65 < 81, √65 lies between 8 and 9 (approx. 8.06).

7Which range on a number line best contains the value of √30?

A.Between 4.0 and 4.5

B.Between 5.0 and 5.5

C.Between 5.5 and 6.0

D.Between 6.0 and 6.5

Explanation: 5.0^2 = 25.0 and 5.5^2 = 30.25. Since 25 < 30 < 30.25, √30 is approximately 5.48, which lies between 5.0 and 5.5.

8Place the following numbers in order from least to greatest: √15, 3.8, ∛64, 11/3.

A.11/3, 3.8, √15, ∛64

B.√15, 11/3, 3.8, ∛64

C.11/3, √15, 3.8, ∛64

D.3.8, 11/3, √15, ∛64

Explanation: Convert values to decimal approximations: 11/3 = 3.666..., 3.8 = 3.8, √15 ≈ 3.873, and ∛64 = 4.0. In order from least to greatest: 3.666... < 3.8 < 3.873 < 4.0.

9What fraction is equivalent to the repeating decimal 0.777... (0.7̄)?

A.7/10

B.7/9

C.77/100

D.7/11

Explanation: Let x = 0.777... Then 10x = 7.777... Subtracting x gives 9x = 7, so x = 7/9.

10Convert the repeating decimal 0.454545... (0.45̄) to a fraction in simplest form.

A.45/100

B.5/11

C.9/20

D.4/9

Explanation: Let x = 0.454545... Then 100x = 45.454545... Subtracting x gives 99x = 45, so x = 45/99. Simplifying 45/99 by dividing numerator and denominator by 9 gives 5/11.
