18;45 = 9
24;16 = 8
I hope this helps
Answer:


Step-by-step explanation:
Let the quotient be represented by 'Q'.
Given:
The difference of a number 'y' and 16 is 
Quotient is the answer that we get on dividing two terms. Here, the first term is 40 and the second term is
. So, we divide both these terms to get an expression for 'Q'.
The quotient of 40 and
is given as:

Now, we need to find the quotient when
. Plug in 20 for 'y' in the above expression and evaluate the quotient 'Q'. This gives,

Therefore, the quotient is 10, when the value of 'y' is 20.
Answer:
C
Step-by-step explanation:
We need common denominator, which in this case is 40.
6*5 is 30 and 4*8 is 32.
We add these up 62/40
Now add the wholes, 5+4 is 9
We have an improper fraction, which will add 1 to 9, causing the answer to be C.
