Question

Lin makes a tile design with 16 tiles. Half of the tiles are red, and half of the tiles are blue. He takes away 4 red tiles. How many red tiles are in the design now

Answer 1

The number of red tiles that remain in the design is 4 red tiles

Explanation:

The total number of tiles = 16 tiles

Number of red tiles = Half of the total number of tiles = 16 × 0.5 = 8 red tiles

Number of blue tiles = Half of the total number of tiles = 16 × 0.5 = 8 blue tiles

Lin takes away, removes, 4 red tiles, therefore, the number of red tiles left in the design is given by

8 red tiles - 4 red tiles= 4 red tiles

The number of red tiles that remain in the design = 4 red tiles.

Answer 2

4 red tiles

Explanation:

- The tile design consists of N = 16 tiles

- Half tiles are red.

Red Tiles = N / 2

= 16 / 2

= 8 tiles

- Half tiles are blue.

Blue Tiles = N / 2

= 16 / 2

= 8 tiles

- He takes away 4 red tiles. With initial 8 tiles, 4 tiles have been taken away. So we are left with:

Red Tiles Left = Total available - 4 Tiles

= 8 - 4

= 4 tiles

- There are 4 red tiles in design now.
