Simple!
Since we can observe that they all have the same denominators (bottom part) we can just observe the numerator (top part)
6 is indeed greater than 5, yes? So we can safely say that
6/8 > 5/8
Now the for the second part.
6 is smaller than 7, yes? So we can make the observation that
6/8 < 7/8
Hope that makes sense! (Be sure to thank me, plz)
P.S. If you want an example of unlike denominators, let me know. <span />
Answer:
x=-3,x1/2
Step-by-step explanation:
f(x)=(2x-1)(x+3)
TI find x intercept/zero substitute
f(x)=0
0=(2x-1)x(x+3)
swap the sides of the equation
(2x-1)x(x+3)=0
when the product of factors equals 0,at least one factor is zero
2x-1=0
x+3=0
solve the equation for x
x=1/2
x+3=0
solve the equation of x
x=-3
The equation has two solution
x=-3
x=1/2
The answer to your question is 2.3
