Question

write each decimal as a fraction. simplify your answer. example: 0.50 solution: 0.50 = 50/100 = 1/2 24. 0.625 25. 0.250 26. 0.045 27. 0.875 write each fraction as a decimal. round to the nearest hundredth if necessary. example: 1/4 solution: 1/4 × 25/25 = 25/100 = 0.25 28. 2/7 29. 7/8 30. 5/9 find the interest earned. example: what is the interest earned on $500 at 8% for 1 year? solution: i (interest) = p (principal) r (rate) t (time) $500 ×.08(1) = $40 31. what is the interest earned on $24,000 at 8 1/2% for 2 years? 32. what is the interest earned on $1,500 at 5.2% for 3 years? evaluate each expression. round to the nearest hundredth if necessary. example: y + 18 when y = 2.1 solution: 2.1 + 18.0 = 20.1 33. x - 6.25 when x = 11.99 34. 6.3a - 5.2b when a = 2.3 and b = 2 35. n ÷ 4.5 when n = 125.25 ng tip when studying for a test, write your own test problems with a partner. then complete each other’s test. double - check your answers.

Explanation:

Step1: Convert decimal a fracción

$0.625=\frac{625}{1000}$

Step2: Simplificar la fracción

$\frac{625\div125}{1000\div125}=\frac{5}{8}$

Step1: Convertir decimal a fracción

$0.250 = \frac{250}{1000}$

Step2: Simplificar la fracción

$\frac{250\div250}{1000\div250}=\frac{1}{4}$

Step1: Convertir decimal a fracción

$0.045=\frac{45}{1000}$

Step2: Simplificar la fracción

$\frac{45\div5}{1000\div5}=\frac{9}{200}$

Answer:

$\frac{5}{8}$
