Brandon eats half the amount of pie that Mollie eats. Yuki eats four times as much pie as Brandon. Mollie eats 1/4 of the pie. How much pie does Anna eat?

Answer: Anna eats 1/8 of pie

Step-by-step explanation: Let total pie = 1

Mollie eats 1/4 of pie

Brandon eats half the amount of pie that Mollie eats i. e 1/2 of (1/4)

⇒1/8

Yuki eats 4 times as much as pie as Brandon i. e 4 * (1/8)

⇒1/2

Total pie eaten by Mollie + Brandon+Yuki = 1/4+1/8+1/2

⇒7/8

Therefore Anna eats (1-7/8)

⇒ 1/8 of pie
