Answer:
x = 0.4
Step-by-step explanation:
Let me rewrite it so it looks better:
[tex]\frac{3}{4} x=\frac{3}{10}[/tex]
The first way is to cross multiply.
30x = 12
x=0.4
The other way is to see that the two numerators are the same except for the x on the left side.
You can see the the denominators are 4 and 10.
You can create a proportion of 4 : 10 and apply it to the fractions.
You get that you have to multiply the left side by 0.4, so x = 0.4
