One-sixth 3227

Two cans hold 20 liters of milk. If we pour from one-sixth to the other, both cans will be the same. How much milk is in each can?

Correct answer:

a =  12
b =  8

Step-by-step explanation:


a+b=20
a-a/6 = b+a/6

a+b = 20
4a-6b = 0

Pivot: Row 1 ↔ Row 2
4a-6b = 0
a+b = 20

Row 2 - 1/4 · Row 1 → Row 2
4a-6b = 0
2.5b = 20


b = 20/2.5 = 8
a = 0+6b/4 = 0+6 · 8/4 = 12

a = 12
b = 8
