(3)/(10) ÷
(4)/(5) equals
(3)/(8).

First, apply this rule: a ÷
(b)/(c) = a ×
(c)/(b). Your problem should look like:
(3)/(10) ×
(5)/(4).
Second, apply this rule:
(a)/(b) ×
(c)/(d) =
(ac)/(bd). Your problem should look like:
(3x5)/(10x4).
Third, simplify 3 × 5 to get 15. Your problem should look like:
(15)/(10x4).
Fourth, simplify 10 × 4 to get 40. Your problem should look like:
(15)/(40).
Fifth, simplify. Your problem should look like:
(3)/(8) which is the answer.
