Name in the same way for multiplication. We will Section 3.3 Methods for Whole Number Multiplication and Division 43 3+15 = q Rr if and only if 143 =q.15+, he left column are multiples of 2. The 1. A student uses duplation to divide: 600 +32 . Their work is shown below. Discuss why the rows with 32, 8, 4, and 1 are crossed out. 120, ...). The next entry in the right out the last row. 600+32 32 64 128 256 16 512 32 024 600 -512 = 88 , 88-64 = 24 , and 24 is less than the divisor 32. Then the remainder is 24. idend 143. Then 600 = 512 +88 = 512+64+24 =16 . 32 +2 . 32 +24 = 18 . 32 +24 . Then 600 +32 =18 R24 . 2. A student uses duplation to divide: 370 +18 . Their partially completed table is shown below. Cross out the appropriate rows, then use the table to determine the quotient and remainder. + 60 = 180 ); 370 +18 18 36 4 72 8 144 16 288 32 576 3. A student uses duplation to divide: 6172 + 70. Their partially completed table is shown below. Cross out the appropriate rows, then use the table to determine the quotient and remainder. 6172 + 70 1 70 2 140 d 143, so we cross out 4 280 the dividend 143. 8 560 16 1120 =8. 32 2240 blbork 64 4480 128 3960 4. Use duplation to divide. Check your work with another student. Your tables should match
