Question 2
Type: MCSA
Divide 4 3/5 ÷ 2 5/8 and simplify to the lowest terms.
1. 1 ¾ 1 / 4
2. 1 5/8
3. 2 2/3
4. 3 3/7
Correct Answer: 1
Rationale 1: Write 4 3/7 as the improper fraction of 23/5 and 2 5/8 as the improper fraction 21/8.Then set up the equation by inverting the second fraction or 23/5 x 8/21 = 184/105. Now reduce the fraction by dividing 105 into 184 or 1 75/100. Reduce the fraction of 75/100 further by 5 until the fraction ¾ is reached. The answer is 1 ¾.

Question 3
Type: MCSA
Simplify the complex equation 13/15 x 200 / 11/17 and reduce it to the lowest terms.
1. 267 22/25
2. 276 25/27
3. 302 23/27
4. 347 19/24 2 / 4
Correct Answer: 1
Rationale 1: First rewrite the equation as 13/15 x 200/1 ÷ 11/17. Next, invert the fraction 11/17 to make the new equation of 13/15 x 200/1 x 17/11. Then reduce the denominator 15 and numerator 200 by 5 so that the new equation is 13/3 x 40/1 x 17/11. Next multiply the numerators and the denominators to reach the fraction of 8840/33. Now divide the denominator 33 into 8840 to reach the number of 267 88/100. Now reduce the fraction of 88/100 by 4 to reach the fraction of 22/25. The final answer is 267 22/25.

Question 4
Type: MCSA
Convert 0.85 to a fraction and reduce it to the smallest terms. 3 / 4
1. 1/4
2. 11/19
3. 17/20
4. 45/50
Correct Answer: 3
Rationale 1: The number of spaces after the decimal point is 2; therefore the denominator for the conversion of 0.85 to a fraction is 100. The fraction would be 85/100. When reducing to the smallest terms, divide both the numerator and denominator by 5 to determine the fraction 17/20.
