Question

20-(1/4)-4-(-24)+(-16)​

Answer 1

$20 - \frac{1}{4} - 4- ( - 24) + ( - 16) \\ \\ \\ = \frac{20}{1} - \frac{1}{4} -4 -( -40 ) \\ \\ = \frac{20 \times 4}{1 \times 4} - \frac{1}{4} -4-( - 40) \\ \\ = \frac{80}{4} - \frac{1}{4} -4-( - 40) \\ \\ = \frac{80 - 1}{4} \: -4-( - 40) \\ \\ = \frac{79}{4} - \frac{ 4}{ 1}-\frac{ -40}{ 1} \\ \\ = \frac{79}{4} - \frac{ 4 \times 4}{1 \times 4} -\frac{ -40}{ 1} \\ \\ = \frac{79}{4} - \frac{ 16 }{4} \\ \\ = \frac{79 - 16}{4} -\frac{ -40}{ 1}\\ \\ = \frac{63}{4}- \frac{ -40}{ 1}\\ \\ = \frac{73}{4} - \frac{40}{1}$
