<u>Answer:</u>
The denominator of a fraction is 4 more than the numerator. The original fraction is 
<u>Solution:</u>
Given that
Denominator of fraction is 4 more than the numerator.
Let’s say numerator of fraction be represented by variable x.
So denominator of a faction as it is four more that numerator will be x + 4
Also given if both decreased by three than simplified result is 

Solving above equation for x
=> 7(x – 3 ) = 6 ( x + 1 )
=> 7x – 21 = 6x + 6
=> 7x – 6x = 6 + 21
=> x = 27
Numerator of fraction = x = 27
Denominator of fraction = x + 4 = 27 + 4 = 31


Hence the original fraction is 
Answer:
64.
Step-by-step explanation:
By proportion to number of orange marbles = (40 / 5) * 8
= 320 / 5
= 64 .
Answer:
x = -(3/2)
Step-by-step explanation:
i'm going to assume that the left side is (2/3)x and not 2/(3x). If so let me know and i'll change it.
(2\3)x =-1 (multiply both sides by 3)
2x = -1 (3)
2x = -3 (divide both sides by 2)
x = (-3) / 2
x = -(3/2)
