1. Know the starting unit and conversion unit. 2. Find out the equivalence ratio. 3. Set up a ratio. 4. Complete the equation by: Setting the different units equal to each other Using the variable X to represent what u are trying to solve Cross multiply Solve for X and use labels.
Ex: 12 tsp = ____cups? 1. Decide what you are starting with: tsp Decide what you are converting to: cups 2.Use the chart to determine the ratio between the two : 1 tsp = 1/48 cup
3. Set up a ratio: 4.Complete the equation. ◦ A. Set them Equal ◦ B. Use X to represent what you are solving for ◦ C. Cross multiply ◦ D. Solve for X; use labels
1. Choose the correct formula for the shape and what you’re trying to find. 2. Plug the known values into the equation and solve for the unknown variable. 3.Use correct units: Perimeter uses just the unit Ex: cm, m, ft, mi Area uses the unit squared Ex: cm^2, m^2 Volume uses the unit cubed Ex: cm^3
