The ratio of red marbles to blue marbles was 5 to 4 if there were 225 in all how many were blue marbles?
The ratio tells us that for every 5 red marbles there are 4 blue ones.
Now the total number is 225.
Out of 9 total marbles, we know 4 are blue.
So we can look at 4 blue/9 total= (x blues which we want to know)/ 225.
This is not hard to solve by cross multiplication.
9x=4(225)
or 9x=900 so x is 100 and there are 100 blue marbles.
Now if that is so, we know the rest of the marbles must be red so there are 225-100=125 red ones.
Let us check that this ratio is 5/4 as desired.
Red/Blue=125/100 and 25 goes into 125 5 times and into 100 4 times so this becomes
5/4.
How else would we do this problem. Since the ratio of 5/4, we know as we said above there are 4/9 blue marbles ( every 4 marbles out of 9 is blue). Now 4/9(225)=4x225/9=100.

A bag contains 6 red marbles 9 blue marbles and 5 green marbles You withdraw one marble replace it and withdraw another marble What is the probability that you do not draw two green marbles 25 denomo?
To calculate the probability of not drawing two green marbles, we first find the probability of drawing a green marble on the first draw, which is 5/20 since there are 5 green marbles out of a total of 20 marbles. The probability of not drawing a green marble on the first draw is 1 - 5/20 = 15/20. Since the marbles are replaced, the probability of not drawing a green marble on the second draw is also 15/20. Therefore, the probability of not drawing two green marbles is (15/20) * (15/20) = 225/400 = 9/16 or 56.25%.
What is the area of the larger hexagon of two similar hexagons which have sides in the ratio 3 to 5 and the area of the smaller is 81 sq m?
ratio of areas = (ratio of sides)² ratio of sides = 3 : 5 → ratio of areas = 3³ : 5² = 9 : 25 → area larger = 81 m² ÷ 9 × 25 = 225 m²
