Question

Kia has 80 tiles. Each tile is white or blue. She arranges the tiles in 8 equal rows. Each row has an equal number of white and blue tiles. How many blue tiles are in each row?

Answer 1

We know that

• There are 80 tiles.

,

• She arranges the tiles in 8 equal rows.

,

• Each row has an equal number of white and blue.

If there are an equal number of white and blue, then we can deduct that there are 40 blue tiles in total.

Now, we divide those 40 blue tiles by 8 rows.

`b=(40)/(8)=5`

Therefore, the are 5 blue tiles in each row.
