🔷 Rule for Dividing Fractions:
To divide two fractions,
multiply the first fraction by the reciprocal (flip) of the second fraction.
That is:
$$
\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}
$$

Now, let’s solve each one:
---
i. $ \frac{3}{4} \div \frac{2}{4} $
Step 1: Flip the second fraction and multiply:
$$
\frac{3}{4} \times \frac{4}{2}
$$
Step 2: Simplify:
- Cancel out the 4s: $ \frac{3}{1} \times \frac{1}{2} = \frac{3}{2} $
✔ Answer: $ \boxed{\frac{3}{2}} $ or $ 1\frac{1}{2} $
---
ii. $ \frac{5}{6} \div \frac{1}{7} $
Flip the second fraction:
$$
\frac{5}{6} \times \frac{7}{1} = \frac{35}{6}
$$
✔ Answer: $ \boxed{\frac{35}{6}} $ or $ 5\frac{5}{6} $
---
iii. $ \frac{1}{7} \div \frac{5}{8} $
Flip the second fraction:
$$
\frac{1}{7} \times \frac{8}{5} = \frac{8}{35}
$$
✔ Answer: $ \boxed{\frac{8}{35}} $
---
iv. $ \frac{5}{6} \div \frac{1}{5} $
Flip the second fraction:
$$
\frac{5}{6} \times \frac{5}{1} = \frac{25}{6}
$$
✔ Answer: $ \boxed{\frac{25}{6}} $ or $ 4\frac{1}{6} $
---
v. $ \frac{1}{7} \div \frac{2}{3} $
Flip the second fraction:
$$
\frac{1}{7} \times \frac{3}{2} = \frac{3}{14}
$$
✔ Answer: $ \boxed{\frac{3}{14}} $
---
vi. $ \frac{1}{6} \div \frac{1}{8} $
Flip the second fraction:
$$
\frac{1}{6} \times \frac{8}{1} = \frac{8}{6} = \frac{4}{3}
$$
✔ Answer: $ \boxed{\frac{4}{3}} $ or $ 1\frac{1}{3} $
---
vii. $ \frac{2}{7} \div \frac{1}{9} $
Flip the second fraction:
$$
\frac{2}{7} \times \frac{9}{1} = \frac{18}{7}
$$
✔ Answer: $ \boxed{\frac{18}{7}} $ or $ 2\frac{4}{7} $
---
viii. $ \frac{1}{6} \div \frac{4}{9} $
Flip the second fraction:
$$
\frac{1}{6} \times \frac{9}{4} = \frac{9}{24} = \frac{3}{8}
$$
(Simplify $ \frac{9}{24} $ by dividing numerator and denominator by 3)
✔ Answer: $ \boxed{\frac{3}{8}} $
