A/5/8 = 3/5 / 2/3

We can take the reciprocal of the denominator, since the denominator itself is a fraction

The above equation can be rephrased as,
(a) / (5/8) = (3/5) / (2/3)

Taking reciprocal

8a / 5 = 3*3 / 5*2

8a / 5 = 9 / 5*2

a = 9 * 5 / 5*2*8

5’s get canceled, 2 and 8 gets multiplied in the denominator.

We will then be left with,

a = 9 / 16


I have also verified it and got the right answer.

Mathematics can uh solve this please ​
guajiro [1.7K]

Answer:

a^3 + 1 = 0

Step-by-step explanation:

We start with the equation:

a + \frac{1}{a} = 1

We want to find the value of:

a^3 + 1 =

We can start with our previous equation and multiply both sides by a:

(a + \frac{1}{a})*a = 1*a\\a^2 + 1 = a

Now we can rewrite our initial expression as:

a = 1 - \frac{1}{a}

Replacing that in the right side, we get:

a^2 + 1 = a = 1 - \frac{1}{a}

Now again, let's multiply both sides by a

a*(a^2 + 1) = a*(1 - \frac{1}{a} )\\a^3 + a = a - a/a\\a^3 + a = a - 1\\a^3 = -1\\a^3 + 1 = 0

So we can conclude that:

a^3 + 1 = 0
