Question

4 4/5 ÷ { 2 1/5 - 1/2 ( 1 1/4 - 1/4 - 1/5)}

Answer 1

Answer:

4 ×4/5÷ (21/5 -1/2(55/20-5/4-4/5))

4 ×4/5÷(21/5-1/2×46/5)

4× 4/5÷(21/5-23/5)

4× 4/5÷ -2/5

4 ×4/5× -5/2

4×-2

-8

Answer 2

Answer:

$4 \frac{4}{5} \div (2 \frac{1}{5} - \frac{1}{2} (1 \frac{1}{4} - \frac{1}{4} - \frac{1}{5} )) \\ = \frac{24}{5} \div ( \frac{11}{5} - \frac{1}{2} ( \frac{5}{4} - \frac{1}{4} - \frac{1}{5} )) \\ = \frac{24}{5} \div ( \frac{11}{5} - \frac{1}{2} ( \frac{25 - 5 - 4}{20} )) \\ = \frac{24}{5} \div ( \frac{11}{5} - \frac{1}{2} ( \frac{16}{20} )) \\ = \frac{24}{5} \div ( \frac{11}{5} - ( \frac{1}{2} \times \frac{4}{5} )) \\ = \frac{24}{5} \div ( \frac{11}{5} - \frac{2}{5} ) \\ = \frac{24}{5} \div \frac{9}{5} \\ = \frac{ \frac{24}{5} }{ \frac{9}{5} } \\ = \frac{24}{5} \times \frac{5}{9} \\ = \frac{8}{3} \\ = \: \: \underline{\underline {2 \frac{2}{3} }}$
