Question

find (a+b)÷(a-b) if a=-3/5,b=2/15​

Answer 1

Answer:

Hi

Step-by-step explanation:

Here given that: a=-3/5 and b=2/15

To find: (a+b)÷(a-b) or (a+b)/(a-b)

=(-3/5+2/15)/(-3/5-2/15)

=(-6+2/15)/(6+2/15)

=(-8/15)/(+8/15)

=-8/15×15/8

=-1

Answer 2

Hence, The value of (a+b)÷ (a-b) = 3/4

GIVEN :

Value of a = -3/5

Value of b = 2/15

To FIND:

Value of (a+b)÷(a-b)

SOLUTION:

we have been given an expression,

(a+b) ÷ (a-b)

putting the values of a and b in the equation we have,

$( \frac{ - 3}{5} + \frac{2}{15} ) \div ( - \frac{3}{5} - \frac{2}{15} )$

According to the BODMAS rule.

We will first solve the operation inside the brackets then operation then division followed by multiplication, addition, and subtraction

$( \frac{ - 6}{15} ) \div ( \frac{ - 8}{15} )$

$- \frac{ 6}{15} \times - \frac{15}{8}$

=

$\frac{ - 6}{ - 8}$

$\frac{3}{4}$

Hence, The value of (a+b)÷ (a-b) = 3/4
