Question

If a = 2/3 and b = 3/4 then find (a×d) / (a-d)​

Answer 1

Answer:

2/3×3/4÷(2/3-3/4)

1/2÷17/12

1/2×12/17

=6/17

Answer 2

Answer:

-6

Step-by-step explanation:

Given details,

a = 2/3

b = 3/4

To find:

(a×b) ÷ (a-b)

So first let us simplify (a×b)

(2/3 × 3/4) = 6/12 when simplified becomes 1/2

Now let usu simplify (a-b)

(2/3 - 3/4), L.C.M of 3 and 4 is 12.

So it becomes 8-9/12 = -1/12

So, (a×b) = 1/2 and (a-b) = -1/2

Now we have to divide these both.

1/2 ÷ -1/12

Here we have to multiply 1/2 with the reciprocal of -1/12.

So it is 1/2 × -12/1 = -12/2 (remember (-) × (+) or (+) × (-) = -)

So it is -12/2 when simplified becomes -6.

So the answer for (a×d) / (a-d)​ = -6.
