If five potatoes together have a mass of one kilogram and eight pears together have a mass of 1200 grams, which has the greater mass a potato or a pear? explain

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.
