Answer:

$9x- 60=10$

Step-by-step explanation:

Given

$\frac{3}{4}x - 5 = \frac{5}{6}$

Required

Rewrite to remove fractions

The denominators in the above expression are 4 and 6.

So, first we take the LCM of 4 and 6

$LCM = 12$

Next, multiply both sides of the equation by this LCM (12)

$12 ( \frac{3}{4}x - 5) = \frac{5}{6} * 12$

$12 * \frac{3}{4}x - 12 *5 = \frac{5}{6} * 12$

$3 * 3x- 60=5 * 2$

$9x- 60=10$

what is the ratio of videos that are dramas to videos that are not dramas? is this a part to part or part to whole ratio?

ser-zykov [4K]

// I am NOT sure about this, but I think it's part to part.

If it was part to whole ratio it will be out of total number of videos.
like ratio of videos that are drama to total videos.....
or ratio of videos that are not drama to total videos.....

You are talking part of each ratio and combining to a different one, so I think it's part to part.

//Again I am not sure about this. But kinda make sense.
