A construction worker was covering the bathroom walls with tiles. He covered three-fifths of the wall with 50 tiles. How many tiles will it take to cover the entire wall?

Respuesta :

It will take 83 1/3 tiles to fill the wall.

Let x be the entire wall:
3/5x = 50

Divide both sides by 3/5:
x = 50 ÷ 3/5
x = 50/1 ÷ 3/5
x = 50/1 × 5/3
x = 250/3 = 83 1/3
