Answer: There are 64 red bricks to made a walkway.

Explanation:

Since we have given that

Total number of bricks = 80

Let the number of grey bricks be x

Let the number of red bricks be 4x

According to question,


x+4x=80\\\\5x=80\\\\x=(80)/(5)\\\\x=16

So, red bricks is given by


4* x=4* 16=64

So, there are 64 red bricks to made a walkway.
