Answer:a is 52    b is 65
Step-by-step explanation:
a:Write 65% as 65100.
65100 of 80 = 65100 × 80.
Therefore, the answer is 52. If you are using a calculator, simply enter 65÷100×80 which will give you 52 as the answer.
b: it is 65 because it is the same question but in reverse which still gives you the same answer.

Answer:
x = 1/3
Step-by-step explanation:
Perform the indicated multiplication:
Clear out the fractions.  The LCD here is 12, so multiply both sides by 12, obtaining:
3(3x - 1) = 24x - 8, or
9x - 3 = 24x - 8
Combining like terms, we get 5 = 15x, so that x = 1/3.
 
        
             
        
        
        
-5 is bigger than -9 because they are negative numbers so they go opposite ways  on the number line so the concept of normal number backwards. hope this helps

1.  You need to make a proportion
2. Your proportion would be 8 over 10 equals X over 15
3. Your equation would be 10x=15(8)
4. 15x8=125
