1 MEP Y7 Practice Book A 2 Arithmetic: Place Value This unit concentrates on place value, both for whole numbers and for decimals, and revises the important techniques of rounding numbers to a given accuracy. 2.1 Place Value and Rounding First note how we write and speak numbers Hundreds Tens Units of Millions Hundreds Tens Units of Thousands Hundreds Tens Units We say "Five hundred and seventy two million, six hundred and forty one thousand, eight hundred and thirty nine." 7451 is 7450 to the nearest 10, since it is nearer to 7450 than to 7460 (see the number line below) is 7500 to the nearest 100, since it is nearer to 7500 than to is 7000 to the nearest 1000, since it is nearer to 7000 than to Note The convention is that '5' rounds up to the nearest 10, e.g. 35 to the nearest 10 is 40. Example 1 Write 2716 to the nearest (a) 10 (b) 100 (c) 1000 (a) 2720 (b) 2700 (c)
