10 Sample 6th Grade MCAS Math Practice Questions

Q1

What is the equation of a line that passes through points \((0, 4)\) and \((2, 8)\)?

A

\(y = x\)

B

\(y = x + 4\)

C

\(y = 2x + 4\)

D

\(y = 2x – 4\)

Show answer and explanation

C
The slope of the line is:
\(\frac{y_2-y_1}{x_2-x_1 }= \frac{8 – 4}{2 – 0}=\frac{4}{2}=2\)
The equation of a line can be written as:
\( y-y_0=m(x – x_0 )→y-4 = 2(x – 0)→y-4 = 2x→y = 2x + 4\)

Q2

What is the volume of a box with the following dimensions?

Height \(= 6\) cm , Width \(= 7\) cm, Length \(= 9\) cm

A

\(63 \space cm^3\)

B

\(126\space cm^3\)

C

\(189\space cm^3\)

D

\(378\space cm^3\)

Show answer and explanation

D
Volume of a \(box = length × width × height = 6 × 7 × 9 = 378\)

Q3

Anita’s trick–or–treat bag contains 14 pieces of chocolate, 15 suckers, 16 pieces of gum, and 20 pieces of licorice. If she randomly pulls a piece of candy from her bag, what is the probability of her pulling out a piece of sucker?

A

\(\frac{1}{13}\)

B

\(\frac{3}{13}\)

C

\(\frac{14}{65}\)

D

\(\frac{16}{65}\)

Show answer and explanation

B
\(Probability = \frac{number \space of \space desired \space outcomes}{number \space of \space total \space outcomes}=\frac{15}{14+15+16+20}= \frac{15}{65}=\frac{3}{13}\)

Q4

In the following rectangle, which statement is false?

A

AD is parallel to BC

B

The measure of the sum of all the angles equals \(360^\circ\).

C

Length of AB equal to length DC.

D

AB is perpendicular to AC.

Show answer and explanation

D
In any rectangle, sides are not perpendicular to diagonals.

Q5

The area of a rectangular yard is 90 square meters. What is its width if its length is 15 meters?

A

10 meters

B

8 meters

C

6 meters

D

4 meters

Show answer and explanation

C
Let y be the width of the rectangle. Then; \(15×y=90→y=\frac{90}{15}=6\)

Q6

Which statement about 4 multiplied by \(\frac{3}{5}\) must be true?

A

The product is between 1 and 2

B

The product is greater than 3

C

The product is equal to \(\frac{75}{31}\)

D

The product is between 2 and 2.5

Show answer and explanation

D
\( 4×\frac{3}{5}=\frac{12}{5}=2.4 \)
\( 2.4>2\)
\( 2.4<3\)
\( \frac{75}{31}=2.419≠2.4\)
\(2<2.4<2.5 \) This is the answer!

Q7

Which of the following lists shows the fractions in order from least to greatest?
\(\frac{3}{4}, \frac{2}{7}, \frac{3}{8} , \frac{5}{11}\)

A

\(\frac{3}{8}, \frac{2}{7}, \frac{3}{4}, \frac{5}{11}\)

B

\(\frac{2}{7}, \frac{5}{11}, \frac{3}{8}, \frac{3}{4}\)

C

\(\frac{2}{7}, \frac{3}{8}, \frac{5}{11}, \frac{3}{4}\)

D

\(\frac{3}{8}, \frac{2}{7}, \frac{5}{11}, \frac{3}{4}\)

Show answer and explanation

C
Let’s compare each fraction:
\(\frac{2}{7}< \frac{3}{8}< \frac{5}{11} < \frac{3}{4}\)
Only choice C provides the right order.

Q8

A car costing $300 is discounted \(10\%\). Which of the following expressions can be used to find the selling price of the car?

A

\((300)(0.4)\)

B

\(300-(300×0.1)\)

C

\((300)(0.1)\)

D

\( 300-(300×0.9)\)

Show answer and explanation

B
To find the discount, multiply the number (\(100\%\)- rate of discount)
Therefore; \(300(100\%-10\%)=300(1-0.1)=300-(300×0.1)\)

Q9

What is the missing price factor of number 420?
\(420=2^2×3^1×…\)

A

\(2^2×3^1×5^1×7^1\)

B

\(2^2×3^1×7^1×9^1\)

C

\(1^2×2^3×2^1×3^1\)

D

\(3^2×5^1×7^1×9^1\)

Show answer and explanation

A
\(420=2^2×3^1×5^1×7^1\)

Q10

If the area of the following trapezoid is equal to A, which equation represents \(x\)?

A

\(x = \frac{13}{A}\)

B

\(x = \frac{A}{13}\)

C

\( x=A+13\)

D

\( x=A-13\)

Show answer and explanation

B

The area of the trapezoid is: area= \(\frac{(base 1+base 2)}{2}×height= (\frac{10 + 16}{2})x = A\)
\( →13x = A→x = \frac{A}{13}\)
