Raheem made a pattern with red and yellow tiles, with the yellow tiles forming 25% of the whole pattern. What is the ratio of the YELLOW tiles to the RED ones in the pattern?

1 : 3

Step-by-step explanation:

The yellow tiles form 25% of the whole pattern.

The red tiles will therefore form 75% of the whole pattern.

Ratio of Yellow tiles to Red tiles is;

25 : 75

Simplest form. Divide each side by 25;

= 1 : 3
