Human: Karen hangs 6 ferns around her house. Each fern has 7 fronds, and each frond has 30 leaves. How many leaves do all the ferns have? Assistant: 
How many fronds are on all the ferns? ** First find the total number of fronds on all the ferns: 7 fronds/fern * 6 ferns = <<7*6=42>>42 fronds
How many leaves are on all the ferns? ** Then find the total number of leaves on 42 fronds: 42 fronds * 30 leaves/frond = <<42*30=1260>>1260 leaves
