Question

red and blue ceramic tiles are laid according to a pattern such that every 18 red tiles used, 7 blue tiles are used. if a total of 350 tiles are used, how many of them are blue? setup a proportion for this scenario( use x for your unknown number of blue tiles).

Answer 1

There are 98 blue tiles.

Explanation:

-this question is solved by proportions, using a rule of three

-For every 18 red tiles used, 7 blue tiles are used, hence, adding 18 and 7 gives you the total tiles, 7 are blue. How many blue tiles are there out of 425?

The rule of three is:

7 blue- 25 total

x blue- 350 total

Applying cross multiplication:

`25x= 7(350)`

`x=(7(350))/(25)`

`x= 98`
