(100 + x) = 3 (20 + x)
100 + x = 60 + 3x
100 = 60 + 2x
40 = 2x
20 = x
Add 20 to both numbers.
Sums are 120 and 40.
120/40 = 3/1
Yes, a number in a ratio must be a whole number.

Yes, a number in a ratio must be a whole number.
To find the number that must be added to -19 to get -11, you can set up the equation: -19 + x = -11. Solving for x, you add 19 to both sides, resulting in x = -11 + 19, which simplifies to x = 8. Therefore, the number that must be added to -19 is 8.
To turn a mixed number into a ratio, you must divide each number into a common denominator.
To determine how many blue counters must be added so that the ratio of yellow counters to total counters is 16, you need to set up the equation based on the current number of yellow counters (Y) and the current number of blue counters (B). Let X be the number of blue counters added. The equation would be ( \frac{Y}{Y + B + X} = \frac{16}{1} ). You can solve for X to find the number of blue counters needed.

Probability is a ratio of two counts: both of which MUST be positive. Their ratio cannot be negative.
The numbers needed adding are 11 and 11 respectively because 16/48 = 1/3
