to divide fractions, take the second one (after the division sign), flip it and multiply

$\frac 78 \div \frac 23 = \frac 78 \times \frac 32 = \cdots$ do you remember how to multiply fractions?

i think so, do i make the denominator the same like with adding fractions?

No

$\frac{a}{b}\cdot\frac{c}{d}=\frac{a\cdot c}{b\cdot d}$
