Hello there! Your questions states: <span>The ratio of the ages of two children is 2:3. If the younger child is 4 years old, how old is the other child? We know when child A is 2, child B is 3. To make child A 4, we must multiply his age by 2. Now we must multiply child B's age by 2, as what you to one side, you must do to the other. 2 * 3 = 6 When child a (the younger child) is 4, child b is 6. Hope I helped! Let me know if you need anything else! ~ Zoe</span>
So if the ratio is 2:3, then the younger child would represent the 2. so it would be 2:3 is 4:x. Thereby, the answer would be 6, because of proportions. To check, simplify 4:6, and you would get 2:3.
