Question

x=1/4;y=3/2 find (x+y)÷(x-y)
​

Answer 1

Answer:

x=1/4

y=3/2

x+y=1/4+3/2=(1+6)/4=7/4

x-y=1/4-3/2=(1-6)/4= -5/4

so,

(x+y)÷(x-y)

=7/4÷(-5/4)

=7/-5

= -7/5

= -1 2/5

Answer 2

first ,

$\sf x + y = \frac{1}{ 4} + \frac{3}{2} = \frac{7}{4}$

then second ,

$\sf x - y = \frac{1}{4} - \frac{3}{2} = \frac{ - 5}{4}$

so , finding (x+y)/(x-y)

$\sf = \frac{7}{4} \div ( \frac{ - 5}{4} ) = \frac{7}{ \cancel4} \times \frac{ \cancel4}{ - 5} = \frac{ - 7}{5}$
