Question

23/4-[3 1/8÷{5-(14/3-11/12)}]

Answer 1

Answer:

$\frac{63}{20} = 3.15$

Step-by-step explanation:

$\frac{23}{4} - ( \frac{31}{8} \div (5 - ( \frac{14}{3} - \frac{11}{12} ))) \\ = \frac{23}{4} - ( \frac{31}{8} \div ( 5 - ( \frac{56 - 11}{12} ))) \\ = \frac{23}{4} - ( \frac{31}{8} \div ( \frac{ 5}{1} - \frac{45}{12} )) \\ = \frac{23}{4} - ( \frac{31}{8} \div \frac{15}{12} ) \\ = \frac{23}{4} - ( \frac{31}{8} \times \frac{12}{15}) \\ = \frac{23}{4} - \frac{31}{10} \\ = \frac{125 - 62}{20} \\ = \frac{63}{20} \\ = 3.15$
