2/3 of a number decreases its 4/8 by 8, what is number?

The equation is 2 by 3 x - 8 is equal to 4 by 8

2 X by 3 is equal to 4 + 6 all by 8

X equal to 4.2

hence the number is 4.2

The correct answer is that the number is 12.75.

Step-by-step explanation:

While this question is written in a convoluted manner, it is asking you to decrease 2/3x by 8. This is the expression for that.

2/3x - 8

And it is saying that it is equal to 4/8, which can be simplified to 1/2.

2/3x - 8 = 1/2

Now we can solve for the x.

2/3x - 8 = 1/2

2/3x = 17/2

x = 12.75
