We can represent this situation by the equation 2x+4x+5x=33.
Then 11x=33, and x = 3.
Then the children's ages are in the ratio 2x:4x:5x, or 2(3):4(3):5(3), or
6:12:15.
Do these 3 ages add up to 33? 6 + 12 + 15 = 33? YES!
The children's ages are 6, 12 and 15 years respectively.
A graph can show that a rate of change is constant as long as the graph is of a straight line.
Any curvature in the line suggests a rate of change that is variable, but otherwise it is constant.
