Answer:
1/6
Step-by-step explanation:
4/9&3/8
4/9x3/8= ?
 Multiply both numerators
= 4 x 3
= 12
Multiply both denominators
= 9 x 8
= 72
Use above values of step 2 & 3, and rewrite as below
= 12/72
so, 12/72 is equivalent to the fraction for 4/9 times of 3/8, and its simplified form is 1/6.
 
        
             
        
        
        
Answer:
RS = 16
Step-by-step explanation:
If a line is parallel to a side of a triangle and intersects the other 2 sides , it divides those sides proportionally.
PR is such a line , then
 =
 =  ( substitute values )
 ( substitute values )
 =
 =  = 2 ( multiply both sides by RS )
 = 2 ( multiply both sides by RS )
32 = 2 RS ( divide both sides by 2 )
16 = RS
