Document Summary
Find lcm( 204, 2. 34. 5. 113 ) based on the prime factorizations. Leave your answer in prime factored form. c. find gcf(204, 156) using the "slide method. " Plot 2. 349 carefully on the number line below. Assume the shorter given tick marks are . 01 apart. Label the endpoints and several of the tick marks with appropriate values, making sure the longer tick marks are labeled sensibly in terms of place value. Add tick marks as needed to show clearly where 2. 349 would be located. b. Using the number line, round 2. 3493 appropriately to the nearest tenth. Explain how the number line justifies your decision for rounding. Label the number lines below in two different ways. Be sure the longer tick marks are labeled sensibly in terms of place value. Identify the following statements as true or false. Use detailed sketches of base seven blocks to justify your answer. Use careful sketches of base ten blocks to explain which is larger, 0. 023 or 0. 03.
