Question

Tana made paper cranes. 2/7 of the cranes yellow and 1/5 of the remainder were blue. The remaining cranes were orange. If she made 70 more yellow cranes than blue , how many orange cranes did she make?

Answer 1

2t/7 = y,= 70+b, (1/5)(5t/7) = t/7 = b, t- total = sum of y,b &g

all rest are green=g, how many green? = 490-140-70 = 280

yellow = 140, blue = 70, total=t = 490
