Answer:
Step-by-step explanation:
a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying. Ex
3

x
=
18
3
=
6
x=
3
18
=6
If I have to , I'll include my fractional equation with the arrows. answer is:
x = 6
They are not equivalent because:
<em>6*3=18 </em>
but...
<em>4*3=12 <- </em>The ratio says "8" not "12"
If you don't get it just say and I'll explain it further. :)
Have an awesome day!
