Answer» Answer: STEP 1 : 5 Simplify — 2 Equation at the end of step 1 : x 1 5 (((—-1)+x)-—)-— = 0 x x 2 STEP 2 : 1 Simplify — x Equation at the end of step 2 : x 1 5 (((— - 1) + x) - —) - — = 0 x x 2 STEP 3 : x Simplify — x Equation at the end of step 3 : 1 5 (((1 - 1) + x) - —) - — = 0 x 2 STEP 4 : Rewriting the whole as an Equivalent Fraction 4.1 Subtracting a fraction from a whole Rewrite the whole as a fraction using x as the denominator : x x • x x = — = ————— 1 x Equivalent fraction : The fraction thus generated looks different but has the same value as the whole Common denominator : The equivalent fraction and the other fraction involved in the calculation SHARE the same denominator Adding FRACTIONS that have a common denominator : 4.2 Adding up the two equivalent fractions Add the two equivalent fractions which now have a common denominator Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible: x • x - (1) x2 - 1 ——————————— = —————— x x Equation at the end of step 4 : (x2 - 1) 5 ———————— - — = 0 x 2 STEP 5 : Trying to factor as a Difference of SQUARES 5.1 Factoring: x2-1 Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B) Proof : (A+B) • (A-B) = A2 - AB + BA - B2 = A2 - AB + AB - B2 = A2 - B2 Note : AB = BA is the commutative property of multiplication. Note : - AB + AB equals zero and is THEREFORE eliminated from the expression. Check : 1 is the square of 1 Check : x2 is the square of x1 FACTORIZATION is : (x + 1) • (x - 1) |

Juliana has $35.00 to spend at the bookstore, where all students receive a 20% discount. Juliana wants to purchase a box that is $28.00 and has a sales tax of 5% after the discount. Which statement below is accurate? A) Juliana needs $0.28 more to buy the book. B) Juliana needs $7.35 more to buy the book. C) Juliana has enough money to buy the book with $5.60 leftover. D) Juliana has enough money to buy the book with $11.48 leftover. |
|
Answer» Answer: Cost of box = 28 cost after DISCOUNT = 28 - (20 PERCENT of 28) = 28 - (28/5) = 22.4 cost including tax = 22.4 + (5 percent of 22.4) = 28 + (22.4/20) = 29.12 dollars Thus she can buy the box and will have 35 - 29.12 = 5.88 dollars leftover |

Arrange the following fraction in decending order 7/12 2/8 3/4 5/8. |
|
Answer» Answer: First we find the L.C.M. of the denominators of the fractions to make the denominators same. L.C.M. of 6, 10 and 20 L.C.M. of 6, 10 and 20 = 2 × 5 × 3 × 1 × 2 = 60 5/6 = 5 × 10/6 × 10 = 50/60 (because 60 ÷ 6 = 10) 7/10 = 7 × 6/10 × 6 = 42/60 (because 60 ÷ 10 = 6) 11/20 = 11 × 3/20 × 3 = 33/60 (because 60 ÷ 20 = 3)
Now we COMPARE the like fractions 50/60, 42/60 and 33/60 Comparing numerators, we find that 50 > 42 > 33. Therefore, 50/60 > 42/60 > 33/60 or 5/6 > 7/10 > 11/20 The descending order of the fractions is 5/6, 7/10, 11/20. 2. Arrange the FOLLOWING fractions 1/2, 3/4, 7/8, 5/12 in descending order. First we find the L.C.M. of the denominators of the fractions to make the denominators same. L.C.M. of 2, 4, 8 and 12 = 24 1/2 = 1 × 12/2 × 12 = 12/24 (because 24 ÷ 2 = 12) 3/4 = 3 × 6/4 × 6 = 18/24 (because 24 ÷ 10 = 6) 7/8 = 7 × 3/8 × 3 = 21/24 (because 24 ÷ 20 = 3) 5/12 = 5 × 2/12 × 2 = 10/24 (because 24 ÷ 20 = 3) |
