Final answer:
Each child gets 1¼ chocolate bars.
Step-by-step explanation:
To find out how much each child gets, we need to divide the total amount of chocolate bars (2½) by the number of children (2). To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. In this case, it would be 2½ * 1/2. Multiplying the numerators and denominators, we get 5/2 * 1/2 = 5/4 or 1¼. Therefore, each child gets 1¼ chocolate bars. So the answer is C) 1¼.
