The answer is A. If there are 30 people and 14 are boys, that means there are 16 girls. So you put 16/14 and simplify so that would be 8/7.
Using proportions, it is found that the average daily requirement for these adults is of 2080 calories.
--------------------
- Percentage problems are solved by proportions, using a rule of three.
- 1560 calories is 75% = 0.75 of the calorie requirement for many adults.
- How much is 100% = 1?
The rule of three is:
1560 calories - 0.75
x calories - 1
Applying cross multiplication:



The average daily requirement for these adults is of 2080 calories.
