2x-4<br> 30<br> 15x - 30<br> PAP

Alex787 [66]

Answer:

$\frac{2}{25}$

Step-by-step explanation:

Given expression,

$\frac{\frac{2x-4}{30} }{\frac{15x-30}{18} }$

=> $\frac{\frac{2(x-2)}{30} }{\frac{15(x-2)}{18} }$

We see that $(x-2)$ is common in both numerator and denominator

hence canceling out we get:-

$\frac{2*18}{30*15}=\frac{2}{25}$

Answer= $\frac{2}{25}$
