<human>:  Kayla and Kylie picked 200 apples total. Kayla picked 1/4 of the apples that Kylie picked. How many apples did Kayla pick?
<bot>: Define a variable ** Let x be the number of apples Kylie picked
How many apples did Kayla pick? ** Kayla picked (1/4)x apples
Set up an equation ** 200=x+(1/4)x
Combine like terms ** 200=(5/4)x
Multiply both sides by (4/5) ** 200(4/5)=160=x apples
How many apples did Kayla pick? ** Kayla picked (1/4)(160)=40 apples
