15/4 and x/3 as a proportion

Sagot :

[tex]x=\frac{45}{4}[/tex]

Explanation

In a proportion both ratios must be equal, so

[tex]\frac{15}{4}=\frac{x}{3}[/tex]

Step 1

solve the equation,

[tex]\begin{gathered} \frac{15}{4}=\frac{x}{3} \\ \text{cross multiply} \\ 15\cdot3=4\cdot x \\ 45=4x \\ \text{divide both sides by 4} \\ \frac{45}{4}=\frac{4x}{4} \\ \frac{45}{4}=x \end{gathered}[/tex]

hence

[tex]x=\frac{45}{4}[/tex]
