College math placement test Exam With 100% Serified Solutions Set up the multiplication vertically. Remember to insert a place holder of 0 when you multiply 416 by 7. Answer is 29,120. - answer416 × 70 = A. 29,536 B. 29,120 C. 486 D. 2,912 E. None of these Start by writing four and two fifths as an improper fraction: 4 2/5 = 22/5 Subtract, and then write the answer as a mixed number: 22/5 − 35 = 22 − 3/5 = 19/5 = 3 4/5 - answer4 2/5 − 3/5 = A. 3 4/5 B. 1 1/5 C. 3 1/5 D. 2 1/5 E. None of these The denominator of each fraction is 5. Since the denominators are the same, just subtract the numerators: 4/5 − 1/5 = 4 − 1 /5 = 3/5 - answer4/5 − 1/5 = A. 3/5 B. 1 C. 4 D. 1/5 E. None of these The number 4 can be written as 4/1, which has the same value as 12/3: 4 − 1/3 = 12/3 − 1/3 = 11/3 = 3 2/3. - answer4 − 1/3 = A. 3 2/3 B. 1/3 C. 3 D. 2/3 E. None of these Use long division: 5 goes into 661 132 times, with a remainder of 1.Use long division: 5 goes into 661 132 times, with a remainder of 1. - answer5 /661 = A. 130; R5 B. 132; R1 C. 132; R2 D. 130; R3 E. None of these The three fractions have a common denominator of 5. Just add the numerators. 1/5 + 1/5 + 2/5 = 1 + 1 + 2/5 = 4/5 This is not one of the answer choices: None of these - answer1/5 + 1/5 + 2/5 = A. 4/15 B. 3/5 C. 1/5 D. 2/5 E. None of these Write each mixed number as an improper fraction. Then, get a common denominator (which is 10). 11/2 + 39/10 = 55/10 + 39/10 = 55 + 39/10 = 9 4/10 = 9 2/5 - answer5 1/2 + 3 9/10 = A. 8 1/5 B. 9 2/5 C. 8 2/5 D. 9 1/5 E. None of these Write the subtraction vertically. I
