Answer:
a)2x-3y
b)4(9a-4)
Step-by-step explanation:
<h3>a)</h3>
we want to expand the following expression:
![\displaystyle - \frac{1}{4} ( - 8x + 12y)](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20-%20%20%20%5Cfrac%7B1%7D%7B4%7D%20%28%20-%208x%20%2B%2012y%29)
well to do so we consider distributive property thus distribute:
![\displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y)](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20-%20%20%20%5Cfrac%7B1%7D%7B4%7D%20%28-%208x%20%29%2B%20%20-%20%20%5Cfrac%7B1%7D%7B4%7D%28%2012y%29)
reduce fraction which yields:
![\displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y) \\ \\ \displaystyle 2x + ( - 3y)](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20-%20%20%20%5Cfrac%7B1%7D%7B4%7D%20%28-%208x%20%29%2B%20%20-%20%20%5Cfrac%7B1%7D%7B4%7D%28%2012y%29%20%5C%5C%20%20%5C%5C%20%20%5Cdisplaystyle%202x%20%2B%20%28%20-%203y%29)
simplify Parentheses:
![\displaystyle \boxed{ 2x - 3y}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Cboxed%7B%202x%20-%203y%7D)
<h3>b)</h3>
in the expression there's a common factor of 4 therefore factor it out:
![\displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%209.4a%20-%204.4%20%5C%5C%20%20%5C%5C%20%20%5Cdisplaystyle%20%20%20%5Cboxed%7B4%289a%20-%204%29%7D)

Answer:
1/3
Step-by-step explanation:
add all of the totals including the missing pair
we now have 24
7+1 is 8
24 minus 8 is 16
24 can be split into 2 groups of 8
and we have 2/3 left. which makes our solution 1/3
