Answer:

x=24

Step-by-step explanation:

By cross multiplying [tex]\frac{4}{5}[/tex] and [tex]\frac{x}{30}[/tex] we get

5x=30*4

5x=120

x=120/5

x=24 (which makes sense because in order to get a denominator of 30 from 5 you need to multiply it by 6, and then the numerator would also be multiplied by 6 (4*6=24) )
