Here are the solutions to your questions: Problem Statement Analysis: Total population = 1700 People above 60 years = 750 Adults between 18 and 60 years = 120 The rest are children (under 18 years). a) The number of children in the community. Step 1: Identify the total number of adults (those 18 years and above). The adults consist of those above 60 years and those between 18 and 60 years. Total adults = People above 60 years + Adults between 18 and 60 years Total adults = 750 + 120 Total adults = 870 Step 2: Calculate the number of children. The number of children is the total population minus the total number of adults. Number of children = Total population - Total adults Number of children = 1700 - 870 Number of children = 830 b) The number of those who are above 60 years. Step 1: Directly state the given information. The problem states that 750 people are above 60 years. Number of people above 60 years = 750 Fraction of children in the community: Step 1: Use the calculated number of children and the total population. Fraction of children = Number of childrenTotal population Fraction of children = (830)/(1700) Step 2: Simplify the fraction. Fraction of children = (83)/(170) Fraction of children = (83)/(170) What's next? Send 'em!
