Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1899 edition. Excerpt: ...with Principle 2, to divide by 5j-J. 100 we cut off two figures, and obtain for quotient 17, with 28 remaining. Since the entire divisor is 300, we must divide this quotient by three. One-third of 17 hundreds = 6 hundreds, with two hundreds remaining; 2 hundreds = 200 units; 200 units plus 28 units = 228 units. Hence, the exact quotient is 5 . Hence, the following rule: 1. Cut off the ciphers from the divisor. 3. Cut off as many figures from the dividend. 3. Divide by the significant figure of the divisor. 4. Make a fraction with the remainder and divisor. To apply the rule: 3. Divide 1898 by 400. Process. Explanation. 400) 1898 Having cut off the two ciphers from 400 and two figures from the dividend, we obtain 18 for quotient and 98 for remainder. Dividing now by the significant figure 4, we obtain 4 for quotient and 200-)-98 for remainder. Making a fraction with the remainder and divisor, we have for the exact quotient 4fg$. Divide: 1. 89 by 10. 2. 376 by 100. 3. 3422 by 100. 4. 5489 by 1000. 5. 6079 by 1000. 6. 71,560 by 100. 7. 97,048 by 100. 8. 57,084 by 1000. 9. 97,068 by 1000. 10. 95,650 by 1000. 11. 7936 by 40. 12. 3079 by 50. 13. 4987 by 300. 14. 5097 by 500. 15. 90,798 by 2000. 16. 96,704 by 3000. 17. 54,970 by 4000. 18. 49,685 by 5000. 19. 74,769 by 6000. 20. 82,546 by 7000. 21. 99,839 by 8000. 22. 99,953 by 9000. 23. 123,456 by 1000. 24. 789,012 by 2000. 25. 345,678 by 3000. 26. 9,012,345 by 40,000. 27. 6,789,012 by 50,000. 28. 3,456,789 by 60,000. 29. 1,982,734 by 70,000. 30. 5,678,901 by 80,000. The Divisor Any Number of Digits. EXERCISES. 1. Divide 25,003 by 48. Process. Explanation. Beginning at the left, we perceive that 48 will divide neither 2 nor 25. We therefore 2qq divide 48 into 250 hundreds, and...show more
