Question

Ridwan work in a factory packing
computers. He packed 1/3 of all the computers in the morning. 1/2
of the computers he packed were shipped out immediately after packing. What fraction of all computers in the factory was shipped out after packing?

Answer 1

Very often the phrase "of the" means multiply.

So he packed 1/3. 1/2 "of the" 1/3 were shipped, this means (1/2)*(1/3) = 1/6 were shipped.
