7th Grade Math Chapter 3: Integers & Rational Numbers

What is an integer?

• A whole number that can be positive, negative, or zero, but does not include fractions or decimals.

• A number that includes fractions and decimals.

• A number that is always positive and whole.

• A number that can be a fraction or a decimal.

How do you represent a negative integer on a number line?

• A negative integer is represented to the right of zero on a number line.

• A negative integer is represented to the left of zero on a number line.

• A negative integer is represented at zero on a number line.

• A negative integer is represented above zero on a number line.

What is the difference between a rational number and an integer?

• All integers are rational numbers, but not all rational numbers are integers; rational numbers can include fractions and decimals.

• All rational numbers are integers, including fractions and decimals.

• Integers are always whole numbers, while rational numbers can only be positive.

• Rational numbers cannot be negative, while integers can be both positive and negative.

What are rational numbers?

• Numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

• Numbers that cannot be expressed as a fraction.

• Whole numbers and their negatives.

• Numbers that are only positive integers.

What is a coordinate point?

• A coordinate point is a single number that defines a position in space.

• A coordinate point is a pair of numbers (x, y) that defines a position in a two-dimensional space, where 'x' is the horizontal position and 'y' is the vertical position.

• A coordinate point is a point that can only exist in three-dimensional space.

• A coordinate point is a representation of a line segment in geometry.

How do you multiply rational numbers?

• Multiply the numerators together and the denominators together, then simplify if possible.

• Add the numerators and add the denominators together.

• Multiply the denominators together and add the numerators together.

• Subtract the numerators from the denominators and simplify.

How do you convert Fahrenheit to Celsius?

• C = (F - 32) × 5/9

• C = (F + 32) × 9/5

• C = (F - 32) × 9/5

• C = (F + 32) × 5/9

What is the profit formula?

• Profit = Total Revenue + Total Costs.

• Profit = Total Revenue - Total Costs.

• Profit = Total Revenue x Total Costs.

• Profit = Total Revenue / Total Costs.

What are the four quadrants of a Cartesian coordinate system?

• Quadrant I (positive x, positive y), Quadrant II (positive x, negative y), Quadrant III (negative x, positive y), Quadrant IV (negative x, negative y)

• Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (positive x, negative y), Quadrant IV (negative x, negative y)

• Quadrant I (negative x, positive y), Quadrant II (negative x, negative y), Quadrant III (positive x, negative y), Quadrant IV (positive x, positive y)

• Quadrant I (positive x, negative y), Quadrant II (positive x, positive y), Quadrant III (negative x, negative y), Quadrant IV (negative x, positive y)

What is the absolute value of a number?

• The absolute value of a number is its distance from zero on the number line, regardless of direction, and is always non-negative.

• The absolute value of a number is the number itself if it is positive, and its opposite if it is negative.

• The absolute value of a number is the square of the number.

• The absolute value of a number is the maximum value between the number and zero.
