Mixed # x denominator + numerator = imp. Fraction
28 x 14 = 392 + 11 = 203
203/14 = 29/2 = 14.5
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Let
y --->Mala's age
x---> sister's age
we know that
 ---> equation A
so
The sum of ages of the sisters is 

substitute equation A in the expression of the sum of ages

simplify

 
        
             
        
        
        
<span>the equation -2x² + 5x -3=0, we notice that the sum of the coefficient equals 0, -2+5-3=0, if such a case happens, the solution of the previous equation will be, x=1 (always) and x= c/a, a=-2, and c=-3, so x=-3/-2, finally, the answer is: the 2 in the denominator should be -2</span>
        
                    
             
        
        
        
There is no difference they are both negative numbers or we could say 25 is higher number then 10 but it negative
