Answer:
To find the greatest number of food parcels Fatima can prepare, we need to determine the greatest common divisor (GCD) of the quantities of each item (tins of beans, chocolate bars, and packets of soup).
GCD(252, 168, 294) = 42
The greatest number of food parcels she can prepare is 42. Now, let's calculate what will be in each parcel.
Number of tins of beans per parcel = 252 / 42 = 6
Number of chocolate bars per parcel = 168 / 42 = 4
Number of packets of soup per parcel = 294 / 42 = 7
Therefore, each food parcel will contain 6 tins of beans, 4 chocolate bars, and 7 packets of soup.
