TEST BANK FOR DOSAGE CALCULATIONS 9TH EDITION BY GLORIA D. PICKAR, AMY PICKAR-ABERNETHY ALL CHAPTERS 1-17 COMPLETE QUESTIONS | COMPLETE WORKING | VERIFIED ANSWERS CHAPTER 1: FRACTIONS AND DECIMALS 1. Arrange the following decimals from largest to smallest: 1.5, 0.25, 1.025. WORKING: Compare the decimals by looking at the digits place by place. 1.5 has 1 in the units place and 5 in the tenths place. 1.025 has 1 in the units place, 0 in the tenths place, 2 in the hundredths place. 0.25 has 0 in the units place. Comparing tenths: 1.5 has 5 tenths, 1.025 has 0 tenths. Therefore, 1.5 is largest, followed by 1.025, then 0.25. ANSWER: 1.5, 1.025, 0.25 Pts: 1 Dif: Recall Ref: Decimals ________________________________________ 2. Arrange the following decimals from largest to smallest: 0.33, 0.045, 0.7. WORKING: Compare the decimals by looking at the tenths place first. 0.7 has 7 tenths. 0.33 has 3 tenths. 0.045 has 0 tenths. Therefore, 0.7 is largest, then 0.33, then 0.045. ANSWER: 0.7, 0.33, 0.045 Pts: 1 Dif: Recall Ref: Decimals ________________________________________ 3. Arrange the following fractions from smallest to largest: 1/2, 3/4, 2/3. WORKING: Find a common denominator. The least common denominator for 2, 4, and 3 is 12. Convert each fraction: 1/2 = (1 × 6)/(2 × 6) = 6/12 3/4 = (3 × 3)/(4 × 3) = 9/12 2/3 = (2 × 4)/(3 × 4) = 8/12 Now compare numerators: 6, 8, 9. Smallest to largest: 6/12, 8/12, 9/12 which corresponds to 1/2, 2/3, 3/4. ANSWER: 1/2, 2/3, 3/4 Pts: 1 Dif: Application Ref: Fractions ________________________________________ 4. Arrange the following fractions from smallest to largest: 5/6, 2/3, 1/2. WORKING: Find a common denominator. The least common denominator for 6, 3, and 2 is 6. Convert each fraction: 5/6 = 5/6 2/3 = (2 × 2)/(3 × 2) = 4/6 1/2 = (1 × 3)/(2 × 3) = 3/6 Now compare numerators: 3, 4, 5. Smallest to largest: 3/6, 4/6, 5/6 which corresponds to 1/2, 2/3, 5/6. ANSWER: 1/2, 2/3, 5/6 Pts: 1 Dif: Application Ref: Fractions ________________________________________ 5. Reduce the fraction 24/36 to its lowest terms. WORKING: Find the greatest common divisor (GCD) of 24 and 36. Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24 Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36 The GCD is 12. Divide both numerator and denominator by 12: 24 ÷ 12 = 2 36 ÷ 12 = 3 Therefore, 24/36 = 2/3 ANSWER: 2/3 Pts: 1 Dif: Recall Ref: Reducing Fractions ________________________________________ 6. Reduce the fraction 18/24 to its lowest terms. WORKING: Find the greatest common divisor (GCD) of 18 and 24. Factors of 18: 1, 2, 3, 6, 9, 18 Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24 The GCD is 6. Divide both numerator and denominator by 6: 18 ÷ 6 = 3 24 ÷ 6 = 4 Therefore, 18/24 = 3/4 ANSWER: 3/4 Pts: 1 Dif: Recall Ref: Reducing Fractions ________________________________________ 7. Convert the improper fraction 17/5 to a mixed number. WORKING: Divide the numerator (17) by the denominator (5): 17 ÷ 5 = 3 with a remainder of 2 The quotient (3) becomes the whole number. The remainder (2) becomes the numerator. The denominator remains 5. Therefore, 17/5 = 3⅖ ANSWER: 3⅖ Pts: 1 Dif: Recall Ref: Improper Fractions ________________________________________ 8. Convert the improper fraction 23/4 to a mixed number. WORKING: Divide the numerator (23) by the denominator (4): 23 ÷ 4 = 5 with a remainder of 3 The quotient (5) becomes the whole number. The remainder (3) becomes the numerator. The denominator remains 4. Therefore, 23/4 = 5¾ ANSWER: 5¾ Pts: 1 Dif: Recall Ref: Improper Fractions ________________________________________ 9. Convert the mixed number 3¾ to an improper fraction. WORKING: Multiply the whole number (3) by the denominator (4): 3 × 4 = 12 Add the numerator (3): 12 + 3 = 15
