to multiply fractions you simply take the denominator of both fractions
and multiply them, do the same to the numerator, and you have your
answer. 
ex. 
2 5 10 
-- * -- = ---- 
4 8 32 
then, of course, you would need to simplify. 
so the answer is 
10(/2) 5 
-------- = ----- 
32(/2) 16 
To multiply mixed numbers, you need to convert them to improper
fractions, multiply and then convert them back to a mixed number. For
example: 
2 1/2 x 5 1/3 = 5/2 x 16 /3 
numerator 5 x 16 = 80 denominator 2 x 3 = 6 
so now you convert 80/6 into a mixed number 
80 / 6 = 13 and 2/6 or, reduced, 13 1/3. </span>

Answer:
Because 4 is a perfect square
Step-by-step explanation:
When simplifying a radical, you have to look for perfect squares. 4 is a perfect square but x is not. Variables are only perfect squares if they have even numbered exponents so the x has to stay in the radical.    
 
        
             
        
        
        
The answer for the expression 0.5x=24 will be x=48
<h3>What is a linear equation?</h3>
The linear equation is defined as the equation having a degree of one or the power of the variable will be one. Linear equation shows the staright line on the graph.
here the given equation is:-
0.5x=24
We can write 0.5 in fraction as 1/2 
1/2x=24
x=48
Hence the answer for the expression 0.5x=24 will be x=48
