2/3a=-24
this the last one that i need on.

You can answer this question in numerous ways but one simple way is by multiplying fractions. 

2/3 of 24 is also 2/3 of 24/1 
To get the answer, you must multiply 2/3 by 24/1 

To do this, you multiply the numerator (the top number) by the other numerator. That is, 2 x 24 . The answer is 48. 

Then, multiply the denominators (the bottom numbers) by each other. That is, 3 x 1. The answer is 3. 

The answer is 48/3. But you must continue simplifying. 

What is 48 divided by 3? 16. 

If you do not understand it that way, think of it in a simpler way. 

Say there are 24 slices of pieces. 

What is one third of those 24 slices? 

24 divided by 3 = 8. 

Now you want TWO thirds. So all you do is multiply 8 by 2. 

That gives you 16. 

I hope i helped, and, if so, please mark as brainliest :P

2/3A = -24
To isolate the 'A', divide both sides by 2/3, which is the same as multiplying both sides by 3/2.
= -24 x 3/2
= -72/2
= -36
So, A is equal to -36
