The table lists some common liquids and their densities. Each density is rounded to the nearest tenth. Substance Density ( cubic grams centimeters ) A Corn Syrup 1.4 B Cooking Oil 0.9 C Ethyl Alcohol 0.8 D Gasoline 0.7 E Water 1.0 Density is written as a decimal number. You can use a number line to compare and order decimals. On a number line, the values increase as you move to the right and decrease as you move to the left. For example, on the number line below, 0.7 is less than 0.9, so 0.7 is to the left of 0.9. D C B E 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 340

Use the table and number line on page 340 to answer the following questions. 1 Which point on the number line represents the density of cooking oil? A. Point E B. Point B C. Point C D. Point D 2 Where on the number line would you plot the point for the density of corn syrup? F. to the left of Point D G. to the left of Point E H. at Point E I. to the right of Point E 3 How many liquids in the table have a greater density than gasoline has? A. 1 B. 2 C. 3 D. 4 4 Suppose you poured liquids A–E into a graduated cylinder. Which is the correct order of liquid layers from bottom to top? F. D, B, C, E, A G. D, C, B, A, E H. A, D, C, B, E I. A, E, B, C, D An object with a density that is less than gram 1.0 cubic centimeter floats in water. List ten items from your home. Predict whether each item will float or sink. Record your predictions. Then test each item. Indicate which items gram have a density that is less than 1.0 cubic centimeter . 341
