To simplify the division between fractions, follow this steps:
Step 1. Turn the second fraction (the one that is dividing the first fraction) upside down:
[tex]\frac{7}{30}\rightarrow\frac{30}{7}[/tex]Step 2. Multiply the first fraction by the one obtained in the first step:
[tex]\frac{14}{15}\cdot\frac{30}{7}=\frac{14\cdot30}{15\cdot7}=\frac{420}{105}[/tex]Step 3. Simplify:
[tex]\frac{420}{105}=4[/tex]The answer is 4.
