Answer :

2kilokaraj
1kg = 1000 grams
Use division:

1000 / 5 = 200 -> 1 potato weighs 200 grams.

1200 / 8 = 150 -> 1 pear weighs 150 grams

Thus a potato has a greater mass than a pear. 
Solutions 

We know that five potatoes together have a mass of one kilogram and eight pears together have a mass of 1200 grams. 

5 potatoes = one kilogram 

eight pears = 1200 grams 

To solve the problem we have to convert 1 kilogram into grams. 

1 kilogram  = 1000 grams 

Now we have 

5 potatoes = 1000 grams 

eight pears = 1200 grams  

The next step is to use division:

1000 ÷ 5 = 200 -> 1 potato weighs 200 grams.

1200 ÷ 8 = 150 -> 1 pear weighs 150 grams

Therefore a potato has a greater mass than a pear.
