In Sakura's garden, for every 555 red flowers, there are 101010 yellow flowers. There are a total of 757575 yellow and red flowers in her garden. How many red flowers are in Sakura's garden?

There are 25 red flowers in the garden.

Step-by-step explanation:

In this problem we have a common issue where the number is repeated 3 times in questions. So I'll sove it using the ratio 5 reds to 10 yellows and the data that there are 75 yellows and red flowers in the garden.

Since we know that for every 5 red flowers in a garden there are 10 yellow ones, then the ratio of yellow flowers to red flowers is

ratio = red/yellow = 5/10 = 1/2

yellow = 2*red

Since there are 75 yellow and red flowers in the garden we have:

yellow + red = 75

2*red + red = 75

3*red = 75

red = 75/3 = 25

There are 25 red flowers in the garden.
