A.) There are many different expressions that can be equivalent to 4/2 and -2/3, but you just need one expression. <em>4/2 is equivalent to 2/1 and -2/3 is equivalent to -4/6.</em>
Reason:
There are two ways you can find a fraction equivalent to another.
1.) First one is by reducing the fraction if possible.
Example: <em>5/10=1/2, 10/30=1/3, 9/16=3/4.</em>
<em />
2.) The second one is by multiplying the numerator and the denominator by the same number, usually by 2 or 3.
Example: <em>1/2 x 2/2 = 2/4, </em> so <em>1/2= 2/4.</em> Another: <em>1/3 x 3/3 = 3/9</em>, so <em>1/3=3/9</em>
<em>That said, 4/2 = 2/1 because it was reduced. While -2/3 = -4/6 because it was multiplied by 2/2. </em>

Answer:
124
Step-by-step explanation:
558/4.5=124
Geometric progresión:
we can calculate any term, using this rule:
an=a₁*r^(n-1)
a₁=the first term
r=the common ratio
a₆=128
r=2
an=a₁ * r^(n-1)
128=a₁ * 2⁶⁻¹
128=a₁ * 2⁵
128=a₁ * 32
a₁=128/32=4
Solution: a₁=4
K(2)+2(-2)=k
2k-4=k
+4 +4
2k=k+4
-k -k
K=4
