How many 250 ml bottles can be filled from 400 liters of water?
Risposta:
#1600# such bottles
Spiegazione:
Each liter of liquid is equivalent to #1000# #ml#.
Hence in each liter, we have #1000/250=(4cancel(1000))/(1cancel(250))# or four (#4#) #250# #ml# bottiglie.
E in #400# liter, we will have #400xx4=1600# such bottles.
