Final answer:
By dividing the total number of fruits by the sum of the ratio parts and multiplying by the specific part attributed to oranges (3), we determine there are 30 oranges in the bag.
Step-by-step explanation:
The question involves a bag that contains a combination of apples and oranges with a specific ratio and a total count. The ratio of apples to oranges is given as 4:3, and the total number of fruits is 70. To find the number of oranges, we can follow these steps:
First, add the parts of the ratio (4 + 3 = 7 parts).
Divide the total number of fruits (70) by the total parts (7) to find the value of one part.
Multiply the value of one part by the number of parts for oranges (3 parts).
Calculating the value of one part: 70 ÷ 7 = 10.
Calculating the number of oranges: 10 × 3 = 30.
So, the bag contains 30 oranges.
