Question

If a = 1/4, b = 3/2 then (a+b)÷(a−b)=?(a+b)÷(a−b)=? ​

Answer 1

Answer:

=(-7/5)

Step-by-step explanation:

=(a+b)/(a-b)

=(1/4+3/2)/(1/4-3/2)

=(1+6/4)/(1-6/4)

=(7/4)/(-5/4)

=(7/4)*(-4/5)

=(-7/5)

Answer 2

(a+b)÷(a−b)

$( \frac{1}{4} + \frac{3}{2} ) \div ( \frac{1}{4} - \frac{3}{2} )$

$\frac{7}{4} \div ( \frac{1}{4} - \frac{3}{2} )$

$\frac{7}{4} \div (- \frac{5}{4} )$

$\frac{7}{4} \times \frac{4}{ - 5}$

$7 \times \frac{1}{ - 5}$

$\frac{7}{ - 5}$

$- \frac{7}{5}$
