1/2 can be rewritten as 3/6, and 2/3 can be rewritten as 4/6 (find the lowest common denominator and in this case it is 6 because 2x3=6). 3/6+4/6=7/6. 12 can rewritten as 24/6, so do 24/6 - 7/6 and you answer is 17/6.

3/8 x 24= 9
Answer:
Part 1 : 
Part 2 :
w=6
l = 10
Step-by-step explanation:
Part 1:
Let the width of the rectangle = w
Length of the rectangle = w + 4
Area of the rectangle is given as
60 Sq Yrds



Hence this expression represents the area of the rectangle. Solving which for w will give us the width of the rectangle.
Part 2:
(w+10)(w-6)= 0
either (w+10) = 0
or
(w-6)=0
or both are zero
(w+10) = 0 ⇒ w = -10
not possible as the dimension can not be 0
(w-6)=0 ⇒ w=6
Hence the width is 6 yards
And thus the length will be 6+4 = 10 yards
