Why is it so important to find the multiple of the divisor that is closest to the dividend? 7,4573=

2
In this lesson, you will learn to divide 4 digit dividends … by using friendly multiples and extended facts of the divisor.

3
Let’s Review 3,0001,0003= x 313= x 1553= x 30103= x Landmark Multiples 15,0005,0003= x 3001003= x 1,5005003= x 6,0002,0003= x 9,0003,0003= x 7,4573=

Core Lesson 3=x2,000 6,000 - 1,457 3=x400 1,200 - 257 3=x80 240 - 17 2,000 + 400 + 80 = 2,485 = 6,000 + 1,200 + 240 7,4573 3,0001,0003= x 3001003= x 1,5005003= x 6,0002,0003= x 9,0003,0003= x Multiples 3001003= x 1,5005003= x Multiples 1,2004003= x 9003003= x 6002003= x 240803= x 270903= x 30103= x 150503= x 3001003= x Multiples 3=x5 15 - 2 + +2 + 5R2R2 + R2R2

6
A Common Mistake 6=x1,000 6,000 - 3,532 6=x600 3,600 - 132 6=x20 120 - 12 9,5326 6=x2 12 - 6,000 3,600 120 12 - 9,722
