praxis 5003 math practice test-A+ Rated Which of the following expresses 3/16 as a percent? A. 0.1875% B. 1.875% C. 5.33% D. 18.75% Option (D) is correct. The question requires an understanding of percent and percentages. To convert a fraction to a percent, it is necessary to multiply the fraction by 100 and add a percent symbol. Since 316×100=18.75316×100=18.75, 316316 is equivalent to 18.75%. (3/16x100=18.75) Which of the following is equal to 4(5−2)2−234(5−2)2−23 ? A. 16 B. 28 C. 76 D.136 B (pemdas) A two-dimensional net of a certain three-dimensional figure includes five faces, nine edges, and six vertices. Which of the following three-dimensional figures is represented by the net? A. Triangular pyramid B. Triangular prism C. Rectangular pyramid D. Rectangular prism Option (B) is correct. The question requires an understanding of three-dimensional geometry. Triangular pyramids and rectangular prisms have four and six faces, respectively. Triangular prisms have five faces: two are triangles, and three are quadrilaterals. Rectangular pyramids also have five faces: one is a rectangle, and four are triangles. Triangular prisms have nine edges, while rectangular pyramids only have eight edges. Which of the following is demonstrated by the figure shown? 1/1 1/2 1/3 1/4 A.When the numerator stays the same and the denominator increases, the fraction increases. B.When the numerator stays the same and the denominator increases, the fraction decreases. C.When the denominator stays the same and the numerator increases, the fraction increases. D.When the denominator stays the same and the numerator increases, the fraction decreases. Option (B) is correct.The question requires an understanding of fractions and how to use geometrical representations to compare fractions. All of the fractions shown are unit fractions; that is, fractions in which the numerator is 1. The models accompanying each of the four given fractions are called tape models. In a tape model, the length of the tape represents one whole. This whole can then be divided into pieces of equal lengths, and the length of each piece represents a unit fraction. The way in which the models are organized and displayed shows that the length that represents the fractional part of the whole becomes shorter as the whole is subdivided into more parts of equal length. This is a pictorial representation that demonstrates that if the numerator of a set of fractions is fixed and does not change, the size of the number represented by the fractions will decrease as the denominators are increased.
