If a/b = 1/3, b/c = 2, c/d = 1/2, d/e = 3 and e/f = 1/4, then find the value of abc/def.
यदि a/b = 1/3, b/c = 2, c/d = 1/2, d/e = 3 और e/f = 1/4 है, तो abc/def का मान ज्ञात कीजिए।

abc/def = (a/d) * (b/e) * (c/f)। a/d = (1/3)*2*(1/2) = 1/3। b/e = 2*(1/2)*3 = 3। c/f = (1/2)*3*(1/4) = 3/8। गुणनफल = (1/3)*3*(3/8) = 3/8।
