Q:
# Add 7.25 L and 875 cL. Reduce the result to milliliters.

Accepted Solution

A:

Answer:7500 ml + 8750 ml = 16250 mlStep-by-step explanation:The first step is converting everything to mililiters, by rules of three. Then we add.In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.Unit conversion problems, like this one, is an example of a direct relationship between measures.First step: 7.25L to mlEach L has 1000ml. So:1L - 1000ml7.5L - x mlx = 1000*7.5x = 7500ml7.25L = 7500mlSecond step: 875cL to mlEach cL has 10ml. So1cL - 10ml875cL - xmlx = 875*10x = 8750ml875 cL = 8750 mlFinal step: adding7500 ml + 8750 ml = 16250 ml
