This issue practices Place Value Review<\/strong> in Pre-Algebra<\/strong>.<\/p>\n\n\n\n Place value describes how the position of a digit determines its value. In a base-ten system, moving one place to the left multiplies a digit’s value by ten, while moving one place to the right divides its place value by ten. For example, the 7 in 72,409 represents 70,000 because it is located in the ten-thousands place. Expanded form makes this structure visible by separating a number into the values of its individual digits.<\/p>\n\n\n\n In this issue, you review how to identify place positions, determine the value represented by a digit, and convert between standard and expanded forms. You also consider the role of zero as a placeholder. A strong understanding of place value supports later work with decimals, scientific notation, estimation, and algebraic expressions involving powers of ten.<\/p>\n\n\n\n\n\n Problem 1.<\/strong> What is the value of the 7 in 72,409?<\/p>\n\n\n\n A.<\/strong> 7<\/p>\n\n\n\n B.<\/strong> 70<\/p>\n\n\n\n C.<\/strong> 700<\/p>\n\n\n\n D.<\/strong> 7,000<\/p>\n\n\n\n E.<\/strong> 70,000<\/p>\n\n\n<\/div><\/div>\n\n\n\n\n Problem 2.<\/strong> Which digit is in the ten-thousands place in 156,230?<\/p>\n\n\n\n A.<\/strong> 1<\/p>\n\n\n\n B.<\/strong> 5<\/p>\n\n\n\n C.<\/strong> 6<\/p>\n\n\n\n D.<\/strong> 2<\/p>\n\n\n\n E.<\/strong> 3<\/p>\n\n\n<\/div><\/div>\n\n\n\n\n Problem 3.<\/strong> Write 9,000 + 80 + 4 in standard form.<\/p>\n\n\n\n A.<\/strong> 9,084<\/p>\n\n\n\n B.<\/strong> 9,804<\/p>\n\n\n\n C.<\/strong> 9,840<\/p>\n\n\n\n D.<\/strong> 984<\/p>\n\n\n\n E.<\/strong> 90,804<\/p>\n\n\n<\/div><\/div>\n\n\n\n\n Problem 4.<\/strong> In 43,912, the digit 3 is in which place?<\/p>\n\n\n\n A.<\/strong> ones<\/p>\n\n\n\n B.<\/strong> tens<\/p>\n\n\n\n C.<\/strong> hundreds<\/p>\n\n\n\n D.<\/strong> thousands<\/p>\n\n\n\n E.<\/strong> ten-thousands<\/p>\n\n\n<\/div><\/div>\n\n\n\n\n Problem 5.<\/strong> Which number has a 6 in the hundreds place?<\/p>\n\n\n\n A.<\/strong> 6,120<\/p>\n\n\n\n B.<\/strong> 4,681<\/p>\n\n\n\n C.<\/strong> 2,604<\/p>\n\n\n\n D.<\/strong> 9,061<\/p>\n\n\n\n E.<\/strong> 16,002<\/p>\n\n\n<\/div><\/div>\n\n\n\n\n Problem 6.<\/strong> What is the value of 0 in 8,052?<\/p>\n\n\n\n A.<\/strong> 0<\/p>\n\n\n\n B.<\/strong> 5<\/p>\n\n\n\n C.<\/strong> 50<\/p>\n\n\n\n D.<\/strong> 500<\/p>\n\n\n\n E.<\/strong> Cannot be determined<\/p>\n\n\n<\/div><\/div>\n\n\n\n\n Problem 7.<\/strong> Which expanded form equals 31,507?<\/p>\n\n\n\n A.<\/strong> 30,000 + 1,000 + 500 + 7<\/p>\n\n\n\n B.<\/strong> 30,000 + 1,000 + 50 + 7<\/p>\n\n\n\n C.<\/strong> 3,000 + 100 + 500 + 7<\/p>\n\n\n\n D.<\/strong> 31,000 + 50 + 7<\/p>\n\n\n\n E.<\/strong> 30,000 + 1,500 + 7<\/p>\n\n\n<\/div><\/div>\n\n\n\nSynopsis<\/h2>\n\n\n\n\n\n
