Sample questions

1. If 3.456 is multiplied by 100, what is the new number?

   1. 34.56
   2. 345.6
   3. 3456
   4. 0.3456
   Show answer

   Answer: B. 345.6

   Multiplying a decimal by 100 shifts the decimal point two places to the right. So, 3.456 becomes 345.6.

2. What is 2.5 x 0.1?

   1. 0.025
   2. 0.25
   3. 25
   4. 2.50
   Show answer

   Answer: B. 0.25

   To multiply decimals, multiply them as if they were whole numbers: 25 x 1 = 25. Then count the total number of decimal places in the numbers being multiplied (one in 2.5 and one in 0.1, for a total of two). Place the decimal point in the answer so there are two decimal places. So, 0.25.

3. Which fraction is equivalent to 0.5?

   1. 1/2
   2. 1/4
   3. 3/4
   4. 2/5
   Show answer

   Answer: A. 1/2

   0.5 means 5 tenths, which can be written as the fraction 5/10. This fraction can be simplified by dividing both numerator and denominator by 5, resulting in 1/2.

4. Which of the following decimals is equivalent to 2/5?

   1. 0.4
   2. 0.2
   3. 0.5
   4. 0.25
   Show answer

   Answer: A. 0.4

   To convert the fraction 2/5 to a decimal, you can either divide 2 by 5 (2 ÷ 5 = 0.4) or make the denominator 10 by multiplying both numerator and denominator by 2 (2x2)/(5x2) = 4/10 = 0.4.

5. Which fraction is equal to 0.75?

   1. 75/100
   2. 75/10
   3. 7/5
   4. 3/4
   Show answer

   Answer: D. 3/4

   0.75 means 75 hundredths, or 75/100. To simplify this fraction, divide both numerator and denominator by their greatest common divisor, which is 25. 75 ÷ 25 = 3 and 100 ÷ 25 = 4. So, 0.75 is equal to 3/4.
