Yvette younger brother just turned 3 years old. fred brother is now 30 months old who's brother is older

You can convert 3 years into months
there are 12 months in one year
so 3 years would be (3*12) months
which would be 36 months

then compare 36 months to 30 months
which is bigger?

36 months
therefore Yvette's younger brother is older.

This is a robot. try again lol. maybe you attached the wrong image.
