Isabella has three times as many green houses as yellow houses. She also has 40 fewer yellow houses than red houses. If she has 90 green houses, how many of her houses are not yellow?
If the number of green houses is three times the number of yellow houses, and there are 90 green houses, then there are 90/3 = 30 yellow houses.
She also has 40 fewer yellow houses than blue houses, meaning there are 30+40 = <<30+40=70>>70 blue houses.
The number of houses that are not yellow is 70 blue houses +90 green houses = <<70+90=160>>160

Isabella'nın sarı evlerin üç katı kadar yeşil evi var. Ayrıca kırmızı evlerden 40 daha az sarı evi var. Eğer 90 yeşil evi varsa, kaç evi sarı değildir?
Yeşil evlerin sayısı sarı evlerin sayısının üç katıysa ve 90 yeşil ev varsa, 90/3 = 30 sarı ev vardır.
Ayrıca mavi evlerden 40 daha az sarı evi vardır, yani 30+40 = <<30+40=70>>70 mavi ev vardır.
Sarı olmayan evlerin sayısı 70 mavi ev +90 yeşil ev = <<70+90=160>>160
