Final answer:
The correct answer is 9 apples. By setting up an equation based on the given ratio of oranges to apples and the total number of fruits, the solution is easily found by algebraic manipulation.
Step-by-step explanation:
The correct answer is option A) 9. To determine the number of apples in the bag, we can let the number of apples be x and then express the number of oranges as 9 times x. As there are a total of 90 fruits in the bag, the sum of the apples and oranges together is 90. This gives us the equation x + 9x = 90. Simplifying, we combine like terms to get 10x = 90, and then divide by 10 to isolate x, giving us x = 9. Therefore, the bag has 9 apples in it.
The correct answer is option B) 27.
Based on the information given, we know that there are 9 times as many oranges as apples in the bag. Therefore, if we let the number of apples be x, then the number of oranges would be 9x.
We also know that there are 90 fruits in total, so we can set up the equation:
x + 9x = 90
Combining like terms, we get 10x = 90.
Dividing both sides of the equation by 10, we find that x = 9.
Therefore, there are 9 apples in the bag.
