Use 30 for trial = = The partial dividend is 180. 180 30 6. 6 × 29 6 96,25 Ans. When the ones' figure is 9, as 29, 39, etc., it is generally easier to use 30, 40, etc., as a trial divisor. 2. 2,499 by 49. PROCESS 51 49)2499 245 49 49 = EXPLANATION. 249 is the first partial dividend. Use 50 for trial divisor. 249504. 4 x 49 196; 249-196 = 55 remainder. When the remainder is greater than the divisor, the divisor will be contained in the dividend a greater number of times. In this case the trial divisor, 50, gives an incorrect quotient. 5 is the first figure in the quotient. 1. 39)498 2. 49)1,251 3. 59)2,039 4. 69)6,506 5. 79)1,848 6. 89)4,058 7. 99)7,612 8. 19)1,742 9. 29)8,787 10. 49)9,898 11. 79)7,979 12. 99)9,999 1. 11)946 2. 11)5,467 3. 11)7,645 4. 11)902 5. 11)8,470 6. 12)867 7. 12)908 8. 12)875 9. 12)1,875 10. 12)648 11. 11)1,080 12. 12)1,080 Find of the following numbers: 13. 253 14. 391 15. 594 16. 1,012 17. 7,337 Find of the following numbers: 18. 1,440 19. 1,728 20. 5,280 21. 2,871 22. 4,410 Find the answer: 23. of $374.40 24.of $ 44.58 25. 1 of $1,000 Analysis - Oral 10 339. 1.
