<human>:  One hundred chips were divided by Ian and Lyle in the ratio 4:6. What percentage of the chips did Lyle have?
<bot>: How many parts were the chips divided into? ** The chips were divided into 4 + 6 = <<4+6=10>>10 parts.
How many chips are in each part? ** Each part has 100/10 = <<100/10=10>>10 chips.
How many chips does Lyle have? ** Since Lyle owns 6 parts, then he has 6 x 10 = <<6*10=60>>60 chips.
What percentage of the chips did Lyle have? ** This is 60/100 x 100 = <<60/100*100=60>>60% of the entire chips.
