Robinson bought a block game for his son. The game contained 20 blocks. His son used 2/5 of the blocks to make a building. How many blocks were in the building?

8

Explanation:

Since the game that Robinson bought contained 20 blocks and his son used 2/5 of the blocks to make a building.

The number of blocks that were in the building will then be:

= 2/5 × 20

= 8

Therefore, the correct answer to the question is 8 blocks.

My best friend Sana is the best he is so kind to people who need it the most. He is always there for me when I need him the most. I remember this one time I was sad because I was being bullied and he stood up to the bully for me. This is just one reason we are best friends.
