The mass of a science textbook is 1.15 kilograms. The mass of a history textbook is 980 grams. Rami makes a stack of 4 science textbooks and a stack of 5 history textbooks. Part A:

Write < or > to compare the masses of the stacks of textbooks.

Mass of History Textbooks
?
Mass of Science Textbooks

Part B:

By how much mass do the stacks of textbooks differ? Enter your answer in kilograms. Complete the explanation of how to find the difference.

The mass of a science textbook is 1.15 kg. So, 4 science textbooks would have a mass of 4 × 1.15 kg =
kg. The mass of a history textbook is 980 g =
kg. So, 5 history textbooks would have mass of
kg. The difference of the masses is
kg.
