54 is shared among three girls in the proportion 11: 5: 2. How many does each girl get

1 answer

To share 54 among three girls in the proportion 11:5:2, we first need to determine the total number of parts in the ratio.

  1. Add the parts of the ratio together:
    \( 11 + 5 + 2 = 18 \)

  2. Now, we can find the value of each part by dividing the total amount (54) by the total number of parts (18):
    \[ \text{Value of each part} = \frac{54}{18} = 3 \]

  3. Next, we can calculate how much each girl receives by multiplying the value of each part by the number of parts she gets according to the ratio:

    • For the first girl (11 parts):
      \[ 11 \times 3 = 33 \]

    • For the second girl (5 parts):
      \[ 5 \times 3 = 15 \]

    • For the third girl (2 parts):
      \[ 2 \times 3 = 6 \]

So, the amounts received by each girl are:

  • First girl: 33
  • Second girl: 15
  • Third girl: 6

To summarize, the distribution is:

  • First girl: 33
  • Second girl: 15
  • Third girl: 6
