Answer:
This one is a bit easy, so if you need a harder one, just let me know. 
((32/48) x (4/6)) / (2/5)
Step-by-step explanation:
1) You can simplify both (32/48) and (4/6) to (2/3).
2) Multiply (2/3) by itself, giving (4/9).
3) Dividing by a fraction is equivalent to multiplying by its reciprocal, or opposite. In this example, the reciprocal of (2/5) is (5/2). Thus, (4/9) x (5/2) = (20/18).
4) Simplify your answer, to (10/9) or 1 and 1/9 (as a mixed fraction).
 
        
             
        
        
        
A geometric sequence is a sequence of numbers that follows a pattern where the next term is found by multiplying by a constant called the common ratio, q:

Answer:
2/5
Step-by-step explanation:
expressing 1 1/2 in an improper fraction:
1 1/2 = 3/2
Hence
(3/5) ÷ (1 1/2)    
= (3/5) ÷ (3/2)   (convert divide to multiply by flipping divisor fraction)
= (3/5) x (2/3)
= (3 x 2) / (5 x 3)
= 6/15 (divide both numerator and denominator by 3)
= 2/5  
 
        
             
        
        
        
2 because you do what is in parenthesis first :)
