What is the first step in the Keep-Change-Flip method? — Keep the first fraction as-is.In KCF: KEEP the first fraction unchanged, CHANGE the division sign to multiplication, FLIP the second fraction (reciprocal).
What is the reciprocal of 3/4? — 4/3.The reciprocal of a fraction a/b is b/a. Reciprocal of 3/4 = 4/3.
What is 1/2 ÷ 1/4? — 2.1/2 ÷ 1/4 = 1/2 × 4/1 = 4/2 = 2.
What is 2/3 ÷ 1/3? — 2.2/3 ÷ 1/3 = 2/3 × 3/1 = 6/3 = 2.
What is 5/6 ÷ 5/6? — 1.Any number divided by itself = 1. 5/6 ÷ 5/6 = 5/6 × 6/5 = 30/30 = 1.
If you divide a fraction by a fraction less than 1, what happens to the quotient? — It becomes larger than the dividend.Dividing by a fraction less than 1 is like multiplying by a number greater than 1, so the result is larger.
What is 4/5 ÷ 2/5? — 2.4/5 ÷ 2/5 = 4/5 × 5/2 = 20/10 = 2.
In the expression (a/b) ÷ (c/d), which fraction do you flip? — The second fraction (c/d) becomes d/c.In Keep-Change-Flip, you flip only the SECOND fraction (the divisor). The first fraction stays the same.
What does GCF stand for? — Greatest Common Factor.GCF stands for Greatest Common Factor — the largest factor that two or more numbers share.
What does LCM stand for? — Least Common Multiple.LCM stands for Least Common Multiple — the smallest multiple shared by two or more numbers.
What are the factors of 12? — 1, 2, 3, 4, 6, 12.Factors of 12 are all numbers that divide 12 evenly: 1, 2, 3, 4, 6, 12.
What is the GCF of 8 and 12? — 4.Factors of 8: 1, 2, 4, 8. Factors of 12: 1, 2, 3, 4, 6, 12. Common: 1, 2, 4. GCF = 4.
What is the LCM of 3 and 5? — 15.Multiples of 3: 3, 6, 9, 12, 15. Multiples of 5: 5, 10, 15. First common = 15. LCM = 15.
What is the GCF of 6 and 15? — 3.Factors of 6: 1, 2, 3, 6. Factors of 15: 1, 3, 5, 15. Common: 1, 3. GCF = 3.
GCF is primarily used to do what with fractions? — Simplify (reduce) fractions.The GCF of the numerator and denominator is used to simplify fractions to lowest terms.
LCM is primarily used for what operation with fractions? — Finding the least common denominator (LCD) to add or subtract fractions.The LCM of denominators gives the least common denominator (LCD), needed to add or subtract fractions.
Which is greater: GCF or LCM (for two numbers greater than 1)? — LCM is always ≥ GCF.LCM is always greater than or equal to GCF. (They are equal only when the two numbers are equal.)
Negative numbers are located where on a number line? — To the left of zero.On a horizontal number line, negative numbers are to the left of zero and positive numbers are to the right.
What is the absolute value of −9? — 9.Absolute value is the distance from zero, always non-negative. |−9| = 9.
Which number is greater: −3 or −8? — −3.On a number line, −3 is to the right of −8, so −3 > −8. A smaller absolute value in the negative direction means a greater number.
What is |0|? — 0.Zero is 0 units from zero on the number line. |0| = 0.
The point (4, −2) is in which quadrant? — Quadrant IV.Positive x and negative y places the point in Quadrant IV (lower right).
What are the coordinates of the origin? — (0, 0).The origin is where the x-axis and y-axis intersect, at coordinates (0, 0).
Quadrant II has what signs for (x, y)? — (−, +).Quadrant II (upper left): x is negative, y is positive. Signs: (−, +).
Order from least to greatest: 4, −1, −7, 0, 3 — −7, −1, 0, 3, 4.On a number line from left to right: −7, −1, 0, 3, 4.
Which of these is true about negative numbers? — They are less than zero.Negative numbers are always less than zero by definition.
