Ответ:
Fraction of water in squash = 1/8
Step-by-step explanation:
Given data:
The total volume of squash = 400 ml
The water in squash = 50 ml
Fraction of water in drink = ?
Solution:
Fraction of water in drink = The water in squash/ Total volume of squash
By putting values in equation:
Fraction of water in drink = 50/400 = 1/8
Conclusion:
Hence the fraction of water in drink is equal to volume of water in total volume of drink which is 400 ml. Water is only 50 ml. So the fraction of water will be 1/8.
