ACTIVITY 1: FINDING ASKED VARIABLE Solve for asked variable. 1. Solve for a in a:1-2:3 2. Solve for x:y in 3:4=x:y 3.Solve for z in 9:3=z:1 4.Solve for b in b: 2= 4:6 5.Solve for w in 1: w = 3:2 Just by simply forming the right ratios and proportion, we can easily solve word problems involving proportions. To have a general guide, in solving word problems, let us follow these steps: 1. Write down the given and form the correct ratio using it. 2. Identify your unknown and represent in using a variable. 3. Write down a proportion which can represent your first ratio equalated to the second ratio which contains the unknown variable. 4. Solve for the unknown variable using the theorems we have learned 5. Once you're sure with your answer, don't forget to always label it.. Activity 2: Try This! While cooking around in a mall, you saw a delicious looking brownie which costs Php 20 per piece. If you are to buy 20 pieces, how much would your total be? a. What is asked in the problem? How would you represent it using the variable? How would you write the ratio and proportion? What is your final answer? Be sure to label it properly
