EXPLANATION:
We are given the ratio of yellow houses to white houses. The ratio is;
[tex]Yellow:White=18:26[/tex]To simplify this ratio, we have to simply divide both values by all common factors.
The common factor for both 18 and 26 is 2. Therefore;
[tex]\frac{18}{2}:\frac{26}{2}[/tex][tex]=9:13[/tex]We cannot simplify further as there is no common factor for both numbers.
Therefore;
ANSWER:
[tex]Ratio=9:13[/tex]
