The groups have 6, 9 and 12 tennis balls
Consider how many parts there are:
in ratio of 2 : 3 : 4 there are 2 + 3 + 4 = 9 parts.
With 27 tennis balls, each part is worth 27 ÷ 9 = 3 tennis balls.
Thus, in the first group there are 2 parts = 2 x 3 = 6 tennis balls,
in the second group there are 3 parts = 3 x 3 = 9 tennis balls,
and in the third group there are 4 parts = 4 x 3 = 12 tennis balls.
To check: 6 + 9 + 12 = 27

You divide the numerator of the ratio by its denominator.
Solving a ratio is quite easy, to say the least. All you have to do is divide the numbers to get the answer.
230, 345 and 460.
Divide numerator and denominator by 3.2 . Arrive at the ratio: 3/8 or 0.375 .
divide both numbers by a common denominator, e.g. 2, such that the ratio becomes 3:5.
Divide 28 cans of soda into two groups so the ratio is 3 to 4
The ratio then will be 18 to 10
12 and 21
12 and 16

One set has 21 pictures and the other has 12.
72/8 = 9 and 3*9 = 27 and 5*9 = 45
