Solve for x: 6 over x equals 4 over 8
Talja [164]

Answer:

For the given expression, x = 12.

Step-by-step explanation:

Here, in the given expression:

6 over x equals 4 over 8.

Now, 6 over x = \frac{6}{x}

and  4 over 8  =  \frac{4}{8}

So, here  \frac{6}{x}   =\frac{4}{8}\\ \implies x = \frac{6 \times 8}{4}  = 12

⇒ x = 12

Hence, for the given expression, x = 12.
