1. Problem: Convert each mixed fraction or fraction to a decimal fraction. 2. Recall that a mixed fraction $a \frac{b}{c}$ converts to decimal as $a + \frac{b}{c}$. 3. Calculate each: 1. $1 \frac{7}{10} = 1 + \frac{7}{10} = 1 + 0.7 = 1.7$ 2. $2 \frac{19}{100} = 2 + \frac{19}{100} = 2 + 0.19 = 2.19$ 3. $5 \frac{101}{1000} = 5 + \frac{101}{1000} = 5 + 0.101 = 5.101$ 4. $7 \frac{1}{2} = 7 + \frac{1}{2} = 7 + 0.5 = 7.5$ 5. $9 \frac{3}{5} = 9 + \frac{3}{5} = 9 + 0.6 = 9.6$ 6. $13 \frac{17}{20} = 13 + \frac{17}{20} = 13 + 0.85 = 13.85$ 7. $18 \frac{14}{25} = 18 + \frac{14}{25} = 18 + 0.56 = 18.56$ 8. $21 \frac{19}{50} = 21 + \frac{19}{50} = 21 + 0.38 = 21.38$ 9. $32 \frac{21}{40} = 32 + \frac{21}{40} = 32 + 0.525 = 32.525$ 10. $43 \frac{9}{125} = 43 + \frac{9}{125} = 43 + 0.072 = 43.072$ 11. $51 \frac{13}{250} = 51 + \frac{13}{250} = 51 + 0.052 = 51.052$ 12. $75 \frac{141}{200} = 75 + \frac{141}{200} = 75 + 0.705 = 75.705$ 13. $16 \frac{51}{500} = 16 + \frac{51}{500} = 16 + 0.102 = 16.102$ 14. $\frac{509}{100} = 5.09$ 15. $\frac{9017}{1000} = 9.017$ 4. Final answers as decimal fractions: 1.7, 2.19, 5.101, 7.5, 9.6, 13.85, 18.56, 21.38, 32.525, 43.072, 51.052, 75.705, 16.102, 5.09, 9.017
