TEAS 7 Math Flashcards

Question 1

Dosage-style word problem

Accepted Answer

Identify the rate, multiply by the quantity, then convert units last. 250 mL × 4 = 1,000 mL = 1 L.

Question 2

Reading a bar graph

Accepted Answer

Compares categories. Always read the title, both axes and the legend before answering.

Question 3

Improper fraction → mixed number

Accepted Answer

Divide: the quotient is the whole number, the remainder is the new numerator. 7/3 = 2 1/3.

Question 4

Percent of a number

Accepted Answer

Convert the percent to a decimal, then multiply. 25% of 80 = 0.25 × 80 = 20.

Question 5

Range

Accepted Answer

Highest value − lowest value.

Question 6

Reading a line graph

Accepted Answer

Shows change over TIME. The slope tells you whether it is rising or falling.

Question 7

1 L = ? mL

Accepted Answer

1,000 mL. Also 1 kg = 1,000 g, 1 g = 1,000 mg, 1 km = 1,000 m.

Question 8

Area of a rectangle

Accepted Answer

length × width.

Question 9

Median

Accepted Answer

The MIDDLE value once ordered. With an even count, average the middle two.

Question 10

Inequality sign flip

Accepted Answer

Flip the inequality when you multiply or divide BOTH sides by a negative. −2x < 6 → x > −3.

Question 11

Perimeter of a rectangle

Accepted Answer

2 × (length + width).

Question 12

Independent vs dependent variable (on a graph)

Accepted Answer

Independent goes on the x-axis (what you change); dependent goes on the y-axis (what you measure).

Question 13

Multiplying signs

Accepted Answer

Same signs → positive. Different signs → negative.

Question 14

Solving for x

Accepted Answer

Do the SAME operation to both sides, using the inverse. 2x + 5 = 17 → 2x = 12 → x = 6.

Question 15

Volume of a rectangular solid

Accepted Answer

length × width × height.

Question 16

Fraction → decimal

Accepted Answer

Divide the numerator by the denominator. 3/4 = 3 ÷ 4 = 0.75.

Question 17

Absolute value

Accepted Answer

Distance from zero, always positive. |−7| = 7.

Question 18

Order of operations

Accepted Answer

PEMDAS: Parentheses, Exponents, Multiply/Divide (left→right), Add/Subtract (left→right).

Question 19

Probability

Accepted Answer

favorable outcomes ÷ total outcomes. 0 = impossible, 1 = certain.

Question 20

Subtracting a negative

Accepted Answer

Two negatives make a positive. 5 − (−3) = 5 + 3 = 8.

Question 21

Unit rate

Accepted Answer

The amount per ONE unit. 180 miles ÷ 3 hours = 60 miles per hour.

Question 22

Rounding to the nearest tenth

Accepted Answer

Look at the hundredths digit: 5 or more rounds up. 3.847 → 3.8.

Question 23

Circumference of a circle

Accepted Answer

2 π r, or π × diameter.

Question 24

Decimal → percent

Accepted Answer

Move the decimal point 2 places RIGHT. 0.75 → 75%.

Question 25

Adding negative numbers

Accepted Answer

Same signs: add and keep the sign. Different signs: subtract and take the sign of the larger absolute value.

Question 26

Multiplying fractions

Accepted Answer

Multiply straight across — no common denominator needed. 2/3 × 3/4 = 6/12 = 1/2.

Question 27

Scientific notation

Accepted Answer

A number between 1 and 10 × a power of 10. 4,500 = 4.5 × 10³.

Question 28

Area of a circle

Accepted Answer

π r² (radius squared, then × π).

Question 29

Percent increase

Accepted Answer

(new − old) ÷ old × 100.

Question 30

Dividing fractions

Accepted Answer

Keep, Change, Flip: keep the first, change ÷ to ×, flip the second.

Question 31

Adding fractions

Accepted Answer

Find a common denominator first, add the numerators, keep the denominator. 3/4 + 1/8 = 6/8 + 1/8 = 7/8.

Question 32

Area of a triangle

Accepted Answer

½ × base × height.

Question 33

1 m = ? cm

Accepted Answer

100 cm. And 1 cm = 10 mm.

Question 34

Mode

Accepted Answer

The value that appears MOST often. A set can have none, one, or several.

Question 35

Estimating an answer

Accepted Answer

Round each number to something easy, then compute — a fast check that your exact answer is sensible.

Question 36

Solving a proportion

Accepted Answer

Cross-multiply. 2/4 = x/6 → 4x = 12 → x = 3.

Question 37

Slope of a line

Accepted Answer

rise ÷ run — how much y changes for each change in x.

Question 38

Percent → decimal

Accepted Answer

Move the decimal point 2 places LEFT. 40% → 0.40.

Question 39

Small unit → big unit

Accepted Answer

DIVIDE. 500 g = 0.5 kg.

Question 40

Converting a mixed number to an improper fraction

Accepted Answer

Multiply whole × denominator, add the numerator. 2 1/3 = (2×3+1)/3 = 7/3.

Question 41

Ratio vs proportion

Accepted Answer

A ratio compares two amounts (3:5). A proportion sets two ratios equal and is solved by cross-multiplying.

Question 42

Big unit → small unit

Accepted Answer

MULTIPLY. 2.5 L = 2,500 mL.

Question 43

Reading a pie chart

Accepted Answer

Shows parts of a whole; all slices total 100%.

Question 44

Mean (average)

Accepted Answer

Add all the values, divide by how many there are.

Question 45

Simplifying a fraction

Accepted Answer

Divide top and bottom by their greatest common factor. 6/8 ÷ 2 = 3/4.
