Final answer:
To find the number of mangoes with a given number of oranges in a fruit stand, we can use a ratio and proportion.
Step-by-step explanation:
In a fruit stand, if the ratio of mangoes to oranges is 3:2, we can use this ratio to find how many mangoes correspond to a given number of oranges.
Given that there are 18 oranges, we can set up a proportion using the ratio:
3/2 = x/18
Cross-multiplying, we get:
2x = 54
Dividing both sides by 2, we find that:
x = 27
Therefore, there are 27 mangoes if there are 18 oranges in the fruit stand.
