4:5: 2. If Lydia and Dan have 77 shells between them, how many shells does Farran have

Answer:

  44

Step-by-step explanation:

You want the number of shells Farran has, if Lydia and Dan have 77 shells between them, and the ratio of shells is ...

  Farran : Lydia : Dan = 4 : 5 : 2.

Ratio

The ratio tells you the number Farran has relative to Lydia and Dan's total is ...

  4 : (5 +2) = 4 : 7

To convert this ratio to an actual number of shells, we can multiply it by 11:

  Farran : (Lydia + Dan) = 4 : 7 = 44 : 77

Farran has 44 shells.
