Finding Equivalent Ratios Given the Total Quantity

Remember that 16 oz = 1lb

What challenges did you encounter? How did you find the value for the third column? Given the third column and one of the first two, how did you find the missing value? Is the backpack weight proportional to the hiker’s weight? Will backpack weight always be proportional to hiker weight? Describe the process for writing the equation

Describe the process for solving using proportions What must be known to find a missing value regardless of the method used? Now that we know the ratio of hiker weight to backpack weight can we find both these parts given only total weight? Find the hiker weight and backpack weight if the total weight is 120lbs.
